You were told wrong. Lemfoerde ("oe" being "o" with two dots above it, or
an
"Umlaut") is the name of a town in Germany, where the manufacturer is. The
factory itself is called "Lemfoerder Metallwaren". Trust me, I am just
looking at the box with lower wishbone bushing for my Alfetta, produced by
them :-)
One more great thing - Rainer Hurtienne told me in an e-mail that they are
planning to start selling parts for 116 series as well.

Doug Bender asked about who has Lemfoerde suspension components.

I was on the hunt about one month ago:  Rainer Hurtienne (frequently
mentioned here) has all of them, including control arms.

They were also kind enough to correct my, and most everyone else's
misspelling of the manufacturer's name:  It's Lemfoerde, not Lemforder.
They should know, they're German.

Colin Verrilli is interested in slightly stiffer rear springs for his '87 
Milano, but is concerned that Ricambi's 17% stiffer "sport" springs, 1 1/3 
inch lower than stock, may bottom out under load.
I don't have a certain answer for a Milano (or GTV-6) specifically, but for
the Alfettas (all types) rear ride height was adjustable by spacers just as
both the fronts and rears were on all 750/101/105/115 Alfas, with three 
different thicknesses of spacers; 11600.25528.05 is 7mm, 11600.25528.06 is 
14mm, and 11600.25528.06 is 21mm. The numbers might (or might not) differ for 
the later cars, but I would be very surprised if the same system did not 
apply, allowing ride height adjustments in several increments of roughly 3/10 
of an inch each, which should be enough of a fudge factor to allow use of the 
17% stiffer "sport" springs with an appreciably more moderate lowering to 
allow for running loaded.

The big washer between the rubber and the nut should hit a raised edge
where the flats of the castor rod end. If you had some corrosion on the
washer or the castor rod, you might have pushed the washer past this point,
but that doesn't seem likely. Mind you, the rubbers do require a lot of
compressing, which is obvious when you compare the shape and size of the
old rubbers and the PU ones. Once the nut on the rod is fully tightened,
the diameter of the rubber should be slightly larger than the diameter of
the washer.

The rattling shifter should be quite easy to cure.

However, these parts can also be obtained from Jon Norman Alfa Parts in
California (Bay Area), for roughly the same price.

Also want to give my vote to Rugh springs, just put in the fronts along
with all of the OEM suspension components, (rears were already
installed) - My GTV handles superbly.  It is not rock hard but I also
feel that an Alfa (at least the 105/115 cars) does not need to be ultra
stiff to achieve optimal handling - even for track applications.

The watts linkage bushings can really let the rear suspension do some 
weird things. You can use a regular shop press no special tools needed. 
To the best of my knowledge the are not any replacement bushings other 
than stock or a complete replacement of the arms with heim joints.

The Dedion pivot bushing is replaceable in the car, but it is a real 
bear- not much room to work and a lot of force required. It was easier 
to remove the whole Dedion tube and press the bushing out and in. Now 
for this bushing there are stock, Super Pro, and the trick SZ heim 
bushing. It all depends on what you are doing with the car for your 
selection. 

My my personal experience the Orange Konis are every good street shocks. 
The stock Spica shocks are too soft. The Yellow Konis are too stiff 
unless set to the initial position, but they are cost much more. The 
Bilsteins seemed to stiff for a street car. No experience with KYB. Good 
Luck.

Subject: creaking Milano/75 front suspension

One side of our 75 creaks when the suspension moves. By a process of
elimination I've isolated the source as part of the torsion bar
assembly. If
I squirt oil between the torsion bar and the lower arm that they wheel
assembly is held on it stops for a few days. Questions
I can see it is an triangular shaped arm that rotates on the end of the
torsion bar, but what are these parts called?
What is sort of bearing surfaces does the front part of the torsion bar
run on?
How do I fix this problem permanently? I guess I dissassemble the torsion
bar some how and lubricate or replace the bearings. How much work is
that? Are any special tools required?
Any suggestions welcomed.
thanks

from Abe Kheraz

Before you go tearing down the torsion bar, you may
want to check the ball joints first.  I did the same
thing as you are thinking about, but the problem was
in the joints.  Apparently they dried up and the metal
surfaces (or whatever surfaces) started to rub against
each other.  Some how when I raised the car to remove
the tire and spray oil on the torsion bar joints, the
surfaces in the ball joints got separated and some
grease got between the them and stopped the creaking
giving me the illusion that what I did cured the
problem.  That will last for a while and then comes
back.  To remedy the problem temporarily is to inject
oil in the ball joints' rubber booths.  That will last
longer than the illusion you get when you spray the
torsion bar.  Good Luck.

Thank you Abe.  I did replace only the right side bearing.  I does
quiet down when I turn right, but I thought that that would mean that
the load is coming off from the right side wheel, therefore the left
bearing is ok, and the right side is the one going bad.  Please let me
know why you think the opposite is true.  Thanks again for your help.

Nelson

Hi again Nelson;

Last year my car was making the same noise as it is
making now.  I noticed then that when I make left
turns the noise goes away.  I let it like that until
it got real bad. I was able to tell where the noise
was coming from when I raised the wheel and let it
rotate.

Currently it is doing the opposite.  I did not get a
chance to raise the car, but I am 99.999% sure it is
the left bearing.  Other ALFA owners on the Alfa
Digest support this theory.

As you know the rear bearings consist of two sections
that are housed in one jacket and opposite each other.
 In straight travel the load is perpendicular on the
axel and the force is trying to separate the bearing
sections from each and therefore they share the load. 
When you make a right turn the force shifts and more
is applied to the outer section reliving the inner one
which is the one that goes bad first.

Later
Abe



Minor clarifications to my post below:
The holes you drill in the iron pipe should go through
both sides and using drill press will give better
alignment of the holes at ech end.

Nelson
If the idea works, please let me know I am going to
change my left bearing when I get back from my
vacation around the end of March.

I figured that much.  What I'll do is the following.  I'll use an old
socket and make a hold thru it.  That way I can still use the torque
wrench to use the proper torque.  I'll let you know how it goes.  Thank

The left bar should have an S or an L stamped on one end.  The right bar
should have a D or an R one one end.  There are also color markings on
the outside of the bar but I can't remember them off the top of my head. 
The rear of the bar has a threaded hole in it for attaching the puller/

My 75 turbo has this caster rod with ball/socket joint for six months. The
first difference is that you feel the bumps in the road trough the chassis a
little better, but I got used to it. It's nothing to be concerned about.
At low speeds you don't feel a difference in steering and cornering. But when
you try to corner at higher speeds, it's perfect. The car feels secure at any
moment while cornering, you can drift and brake while cornering without losing
the car. My car is lowered at the maximum, in front and rear, and my front
tires always used to wear in at the inside in short time. Since I use this caster
ball/socket the front tires don't wear only at the sides anymore, the wear
has become even, like it's supposed to be. So not only the steering will be
improved, but also the breaking, because the caster will always be at 4,5
degrees. The wheels will not tend to be displaced backwards while braking.
I personally don't understand why this type of connection isn't used
standard on this car. It's easy to install (3 hours) and it's a lot of fun to drive.

        I would expect your average alignment shop would just get it close to
spec or the specs you gave them (if they even do that). Your front toe
is off from both specs. For my street GTV6 I run zero toe, -.75 camber,
and around 3 deg caster. Unless you either shorten the arm spacers or
use an offset upper A-arm bushing, you will not be able to take neg.
camber out of the alignment. The problem with caster adjustment is that
if the caster rod has not been adjusted recently the adjuster will be
stuck in place. I would not accept such a alignment, but there may be
items you need to take care of on the car to make it possible to
correctly align.

Firstly, it sounds like your 70mph+ shake is something that I've heard
GTV6's do frequently (including mine).  Mine still does it, but was
improved after an alignment (which was probably done wrong anyway--perhaps
it should have eliminated the problem).

Your clunks sound to me like worn/broken transaxle mounts or misadjusted
"burnout bolt" (I don't know the proper term for that one).  By "burnout
bolt" I refer to the threaded rod on top of the driveshaft tunnel in front
of the back seat (or, from the bottom, right behind the rear donut).  It
has a slot for a screwdriver in the top, but once you adjust that to
eliminate the problem, it is critical to adjust the locknut on the
underside accordingly.  This is a huge bitch, but I believe the locknut
actually bears the load.  If you do like I did and ignore the seized
locknut you will eventually break the assembly that this thing is threaded
into.  While I'm on the subject, anyone have any tips for adjusting the
afformentioned locknut?

BTW, thanks to all who helped with Jake's ignition switch.  He's going to
get a new one and have to pull the way-ill two-keys-one-car gag as the
switch assembly does not seem to want to come apart.  Any tips would be
appreciated, but it looks like you're supposed to drive out a rod, but this
one is stuck.

The supersport bars are much more difficult to install because of the
problem you stated.  Although it is possible to pry the "A" arm down with a
lever, it is also very awkward especially if you try several times to get
the height right.  It would be nice if you could put the bolt in from the
engine side but of course the sump is in the way.  A solution I use is
to have some special studs machined with nuts on both ends.  I slip the
studs in the frame before I mount the "A" arms and use Loctite stud lock
on
all the nuts for safety.

Subject: GTV6 torsion bar adjust/steering

Joe Elliot asked the procedure for lowering his GTV6 front ride height:

Here's how it's done:

First measure the front ride height at both wheels, I use ground to TDC
of wheel opening, then decide how much you want to lower it (be
conservative if staying with stock T bars)

Then, under the car mark the current position of the teeth of the tbars
in relation to the splined sockets, once you have done this, take the
amount of lowering you want remove and rotate BOTH ENDS of each torsion
bar and towards the center of the car for 4 teeth for each quarter inch
you want to lower it (apx) so If you want to lower the car a full inch,
rotate the torsion bar 16 teeth from the original marks.

Once this is done, drive the car around the block and recheck ride
height in the same flat level surface you did the first time. Adjust as
necessary

If your're torsion bars have never been out they may be stuck inside,
spray lubricant into the sockets for a couple of days before you plan to
do it, and drive around to work it in. I've had to heat the sockets with
a torch in many cases to free the bar.

AFAIK, 3 ways to "lighten" the GTV6 steering

1-Run too high a tire pressure-BAD

2-Fit a bigger steering wheel-BAD, the OE one is already boat like

3-Retrofit Milano Power steering-The only truly viable way, IMHO
4- Bring Castor closer to "0". ED

Hi Bryce,

 Hight: depends on how much you want to raise your car

The rings are not available from any shop, but you can manufacture
them yourself as there are no special shapes; they are in fact just 2 big
washers!

I have 2 sets: A 10 mm set made out of polycarbonate and a 15 mm
set made out of aluminium. But steel can also be used.

Mounting:
From below the rear suspension consists of: DeDion axel - specially
shaped saddle for rear spring - rear spring - specially shaped steel
ring - specially shaped rubber ring - chassis.
The rings must be placed between the specially shaped rubber ring and
the chassis (these are parallel to each other; thats why a 'flat' washer will
fit).
When you have removed the rear spring also remove the specially shaped
steel ring and the specially shaped rubber ring (these two tend to stik to the
chassis). Place them on top of the rear spring, place the new ring on top
of the assembly and tie them together with the spring using self-adhesive
tape. The tape does not add any strength to the final construction; it is
only used to keep all those rings on top of the spring until the assembly
is mounted ! Please make sure to allign the rear spring and the specially
shaped steel ring/the specially shaped rubber ring as the end of the spring
must fit the cut-out in the steel ring/rubber ring.

Hope this will help you. Good luck !!

In AD7-195 Jake Thomas, who has a GTV6 which has been lowered beyond the point
of sanity by a previous owner, opens a large, and very old, can of worms about
torsion bar front suspensions on the transaxle cars.

>> I know that the front height is controlled by the torsion bars but lack the
instructions to adjust them. Can someone please post instructions, or point me
to where they can be found?<<

In the shop manual. Any shop manual, preferably GTV-6, but Milano will do
equally, as will an Alfetta manual, by Haynes, Autobooks, the factory, cribbed
reprint, whatever. The process and logic are the same, the values are the same
or very close, differing slightly with the lighter-nosed cars. 

>> Secondly, I'm wondering what the "correct" height really is.  The N.
American and European factory specs were different,<<

As far as I know this is totally incorrect. Front suspension settings are
checked by subtracting the height of the bottom of the steering knuckle (or
lower ball joint assembly) from the height of the wishbone pivot-mounting,
with the car loaded to specified values. The resulting "trim value" is, as far
as I can recollect, 44 mm +/- 5 mm, for Alfettas, Milanos, GTV-6s (and I
assume Giulietta Nuovas, 90s, 6s) but check your manual. If you find a
different one for your country (or for your county, for that matter) use it.
This value is unaffected (as measurements from bumper, drain plug or some
other chassis point to the ground would be) by wheel or tire size or wear,
sagging motor mounts etc. 

A caution: torsion bars almost invariably have pre-twist; a given load will
twist one further in one direction than in the other. For this reason if the
painted code marks (yellow for the left bar, blue for the right bar) are no
longer present pray that you can find a stamped code L (for 'left') or S (for
'sinister') on one and a code R (for 'right') or D (for 'dexter') on the
other, preferably on the left and right sides of the car, respectively. 

The bars have 35 splines at the front and 34 splines at the rear, allowing a
fairly precise vernier adjustment. Moving both the front and the rear by one
spline raises or lowers the suspension about a tenth of an inch. The trim
value (measured in the second paragraph above) is increased by rotating the
right bar clockwise and the left bar counterclockwise, or decreased by doing
the reverse. Moving one end one tooth while leaving the other end alone
changes things by about thirty-five tenths of an inch, which coincidentally
corresponds to the differences between front bumper height and rear bumper
height which Jake measured on his car: 
>13", bottom of front bumper
>16.5", bottom of rear bumper.

If all this isn't clear (quite likely) and if I might have gotten it ass-
backwards (entirely possible) pour a coffee (no, not another beer), sit down,
and read the manual again.

The important thing to understand is that there is nothing haphazard about the
process. Too many people have said that you just take it apart, put it
together some other way, and see if it looks right, and do it again until it
does look right. Wrong. 

As for the optimum amount to leave it lowered from stock to correct the
aesthetic and handling errors of those dunces at the factory, you will have to
get that from someone else. I'm gone.

Cordially, 

John H.

"transsexual." This I refuse to do.

tire size was 195/60 HR 15 until the last year in which a very abnormal size
of Michelin tire and its own very abnormal wheel was adopted. The owner's
manual is a very useful thing to have. A photocopy, if an original is not
available.

He writes further:
>>The details on spline adjustment are very helpful but the information I'm
really looking for is how to get to the part where I do the adjusting.  I see
some bolts at the back end of the torsion bar and a big rectangular bar
running across underneath.  But I don't want to start loosening and hammering
until it's off-loaded and, so far, that doesn't seem to be the case.  I have
visions of small or, worse, large parts flying across the garage, never to be
seen again, and so some advice from those who've been there would be
reassuring.<<

What the shop manuals will tell you is:
1. Jack up the lower suspension arm until the upper arm moves away from the
rebound stop.
2. Undo the castelated nut, then using a balljoint separator disconnect the
lower suspension arm from the stub axle carrier.
3. Lower the jack under the suspension arm, after first placing a stand under
a jacking point to keep the body in a raised position.

That covers the big worry. The lower A-arm is held up by the limp torsion bar,
nothing is under torsion, and no parts are going to go anywhere that gravity
and your tools don't put them. Nothing.

Great as the digest is, I must make a plug for warm-body, face-time type car
clubs. If you are sitting in the pizzeria chatting with seven or eight other
guys waiting for the lady to bring the beer, one or another of the people with
dirt under his fingernails probably usta have an Alfetta and probably would
lend you his dirty old shop manual. He might even give it to you. All of the
systems except the engine are essentially the same, just some beefier on the
GTV-6. Changing giubos, pulling transmissions, adjusting ride heights didn't
change from the first 1974 Alfetta to the last Milano. The ARA is an excellent
club if you are in that neighborhood, AROC and its local chapters anyplace in
the USA, other national Alfa clubs in other countries.

I've got to get some CarDisks too, don't have one yet, just old paper stuff.
The CarDisks contain an ENORMOUS amount of interesting and useful material,

choice, but given portability, display resolutions, working conditions where I
work, and the costs of things I might screw up I would go for a manual first,
or pay the going shop rates to someone else. I believe in paper; I bought my
164 shop manual (which had been given to him by ARDONA) from a mechanic at an
Authorized Dealership who "din't need no manual to work on no car." Never took

Subject: Milano torsion bar nightmare repost (long)

I tried posting this twice before but it never seemed to get through when
the list went down earlier this week. So here it is once again, hope someone
can point out what went wrong this past weekend.

So I decided to go for it and perform this minor adjustment to my Milano's
ride height myself. It started around the middle of last week, when I
searched for a screw type ball joint separator that would work on my car. I
found none in my area, just a bunch of pickle fork separators. It was too
late to order the ridiculously expensive one from IAP, so I thought I'd go
to all my local auto parts stores in the South Bay (near L.A.). Well no one
had this thing, but I happened to have a screw type ball joint separator
from my old Miata. It didn't have a big enough mouth to get around the top
of the Milano ball joint, so I whipped out my dremel and proceeded to
vaporize two grinding disks while enlarging the mouth of my ball joint
separator (I'll post pics on the twiki site). Once this was finished I
thought I was home free, just an M10x1.25x60mm bolt to purchase and I'd be
in business.

Here things start to go wrong. Saturday morning while driving around looking
for the ball joint separator I was only able to find a 40mm version of this
tricky bolt, and it was only of grade 8.8 (which I was to learn more about
later). So I got home and took the front suspension apart, separated the
lower control arm from the steering knuckle and began to pull the torsion
bar to the rear of the car. It was very tough going the whole way. This
t-bar just didn't want to move, every 1/8 turn of the ratchet required large
amounts of force. I initially used a stack of washers, but once the t-bar
came out past the cross member I was stuck because the sockets I planned to
use as spacers were all longer than the 40mm bolt I was using. Eventually I
found a 50mm version of the bolt but still of only grade 8.8. I put it
inside a large socket and began to pull. This bolt immediately stripped. Now
the inside of the t-bar was screwed. The only bolt I could get into it was
the old 40mm one (I guess it was stripped in a similar fashion). So I gave
up and went to bed, but still thinking about how to get a good strong bolt.

Sunday I woke up with the brain on over drive. It finally dawned on me to
look up fasteners in the phone book. I dialed every number but they were all
closed. Finally a clerk at a local Lowes said he didn't have what I needed
but another place Lovelady Hardware did. I went over there and they were
opened, and I bought three M10x1.25x60mm grade 10.9 bolts. And not one of
them would fit in the stripped t-bar on the left side. So I finally figured
out how to use that harmonic balancer puller that was mentioned before. I
used my only 40mm bolt to cinch down the puller to the t-bar. Then used two
bolts on the outside of the puller to push against the cross member and pull
the t-bar out the remaining 3 or 4 mm to free it. Once it was out I lubed it
w/anti-seize and rotated it 8 splines clockwise and easily plugged it back
in.

Halfway done and it is now about 2pm Sunday. Moving to the right t-bar I
take apart the suspension and apply my fresh M10x1.25x60mm grade 10.9 bolt
to the right t-bar. It comes out like buttah (oh I sprayed the inside of the
t-bar threads w/penetrating oil first, it may have helped some, but the it
couldn't have accounted for everything). But one problem I notice
immediately is that it is much harder to rotate this t-bar. The left bar I
was able to rotate by hand but the right one required a pair of channel
locks applied to the splines ( I was very careful to only work at the back
of the splines and not to crush them ). This should have served as a warning
to me. Anyway I anti-seized the splines and rotated it 10 splines
counter-clockwise (the ride height was uneven to begin with). So the goal
was to lower the car .8" on the drivers side and 1" on the passenger side.

Now I think I'm home free, just plug it all back in and reassemble
everything.... Not so fast grasshopper, you forgot to pray to the Italian
goddess of mechanistic insanity. Not only should I have prayed but I should
have offered a chicken in sacrifice or something. The t-bar won't go in very
far. I can't even get it to contact the lower control arm in the front.
After much pounding, cursing and sweating I finally back the thing out
again. Apparently the rubber coating on the bar in between the front and
rear splines got pushed into the rear t-bar mount and then was pinched when
I tried to push the t-bar back to the front. I tried trimming it but that
didn't work, so I tried once again to push the t-bar to the front of the
car, this time I was able to get the bar to seat in the rear mount. After
another hour of trying to get the bar into the front control arm I
eventually succeeded. By now its about 7pm on Sunday.

I reassemble the front suspension, put the wheels on and drop the car off
the jack stands. And what do I find...... the bloody @#$@$#@$ &%^%$&$%@ing
car is now about 1" higher in front than it was before I started!

I'm so mad now I could just take a sledgehammer to the car! Before I commit
ritual automotive seppuku with a pickle fork and an anti-seize cocktail (for
good measure) could someone clue me in on what went wrong? I had three
different sources on which way to turn the t-bars: the Milano shop manual,
the Shankle torsion bar installation instructions and the article at the
alfa twiki site. They all appeared to say that when viewed from the rear you
rotate the left bar clockwise and the right bar counter clockwise to lower
the car.

So I was beneath the passenger seats looking towards the front of the car I
rotated the left bar (under the drivers seat) 8 splines clockwise at both
the front and rear mount points. So with my inital marks in the 9 o-clock
position I rotated them clockwise towards the center of the car. The right
bar (under the passenger seat) was rotated 10 splines counterclockwise at
both the front and rear mounts. With my initial marks at the 3 o-clock
position I rotated the bars counterclockwise from 3 to 2 to 1 to 12 o-clock
positions and so on.

What did I miss understand or do wrong? I remember that the previous owner
of this car said he had a mechanic adjust the front ride height, could that
have had anything to do with this going so terribly wrong?

Derek,

[contains obligatory Fred content that I haven't seen echoed yet, and
probably the best piece of advice I ever saw from him.]


> So now the question is what is the appropriate type to get?


You need a screw-operated one that is large enough to fit over the eye of
the a-arm that retains the ball-joint. Either the cup-type or lever type
will work, provided they're big enough.


> Also I'm not so sure about the articles I've seen that

That won't work. Assuming you've got something bolt the balancer to, a
balancer will attempt to push the bar out the front. With the lower a-arm
still on the car, it's got nowhere to go. All you need is a large socket
(same one as crankshaft nut works just fine). A stack of large, thick
washers to "extend" the socket", and an appropriate bolt to screw into the
back of the torsion bar. Exact size escapes me, but it's the same as the one
that holds the inner end of upper a-arm onto the car (M10x??). I happen to
have some of these lying around - you'll need to go out and get one if you
don't want to pull the upper arm to re-use this bolt.

Procedure:
- - loosen wheel nuts
- - jack up front of car
- - support on jack stands
- - remove wheels
- - disconnect shock absorber from lower a-arm
- - separate ball joint (either upper or lower. It doesn't
  matter which, but I've found the upper ones are easier, but
  it makes the lower a-arm more unwieldy with the steering
  knuckle attached.)
- - pop plastic cover off rear of torsion bar
- - place large socket and washers over rear of torsion bar
- - screw bolt into rear of torsion bar
- - as the bolt head bears on the washer stack, it pulls the
  torsion bar out backwards
- - when you run out of travel (do not over tighten), unscrew and
  add more washers to give you more travel. repeat as
  necessary.

Now you can adjust height and then do everything up again.

A couple of rebuttals:


> You'll spend $100 of that $200 in tools alone.


The ball joint splitter, the socket, and the bolt are the only special tools
you'll need. Nothing like $100 (assuming you already have basic
spanners/sockets/jack/stands).

<Fred content>
Get the shop manual!
This will take it close to $100. cardisk, IAP, centerline, etc all have
manuals. Once you have the manual, life becomes much simpler.

In AD7-3012 Brian Shorey mentioned, re front wheel bearing noises, that

<<Ride Height Adjustment 
Ride height adjustment is carried out by rotating the torsion bars with
respect to the indices
on the front lower A-arms and rear mount within the cross member.  The
bars are provided with a
different number of splines (35 front, 34 rear) at each end, essentially
a vernier scale,
allowing precise adjustments to be made.  When removing the bars, take
care not to switch them
over.  The bars are marked by the following code: Left by a yellow mark
and the letter S or L:
right by a blue mark and the letter D or R. You shouldn't have to worry
about this since the
bars don't need to be fully removed to be adjusted, but I included it
here just in case.  

Using a marker, grease pencil or scribe, mark the position of the
factory indices on the A-arm
and cross member in relation to the splines on the bars.  By employing
the torsion bar removal
tool or your substitute (you cheapskate), withdraw the torsion  bars to
the rear so that the
splines are completely free.  Complete the ride height adjustment by
rotating the torsion bar
by one tooth at each for every 1.5 mm to 2.0 mm of required adjustment. 
Viewing the bars from
the rear, rotate the right side bar counterclock  wise to lower the car
and clockwise to raise
the car.  You adjust the left bar in the same manner, but rotate the bar
clockwise to lower the
ride height and counterclockwise to raise it.  

Use this formula to correct ride height: (amount of required correction
in inches) divided by
.059  (number of splines rotated).  Round off the number of splines to
be rotated, such as 10.4
is read as 10.  

Reinsert the bars, remembering to permanently mark the original factory
indices, and
temporarily mark your new splines corresponding to the factory indices. 
These may be marked
permanently once you've verified the new ride height, but always
distinguish them from the
original factory reference marks. >>

Subject: Milano Handling Fixed (my fault)

After replacing every bushing in the car, I was disappointed to find on 
my first test drive that the car handled horribly.   I knew I needed a 
re-alignment, but I figured that it couldn't have been that bad.

So I took it in for an alignment...  Got a call back saying they did the 
best they could, and asked if it was ever in an accident.   The rear 
wheels weren't lined up with the chasis...

I picked it up, only to find marginal improvement.  It was still spooky 
to drive.   As I plotted driving off a cliff to end my sorrows on the 
way home, I thought some more about the problem.    The rear end had a 
mind of it's own.  Was there something wrong with the Watts links?

Well by the time I got home (just a few minutes) I figured it out, and 
pulled out the shop manual to confirm.   I had the watts links connected 
backwards.    I was looking at the wrong picture in my manual when I 
re-assembled, and had incorrectly interpreted the witness marks I had 
made on the links before I removed them.

*sigh*

15 minutes later I reversed the links and was back on the road.   The 
handling was restored, and I was able to enjoy the added stiffness of 
all the new bushings.

While I may be hanging my head in shame, I'm tickled that the problem 
was as easy to solve as it was.

Les Singh Said:

>stupid suspension ball joints  - top arm has bj rivetted in - why?! 
>bottom bj has a spline locator at the top  -- why?!

Yes those idiots at Alfa. I saw a guide on replacing a Honda Civic Si
upper balljoint. Just simple bolts. And fortunately I have replaced the
upper balljoint. I can do it, but it involves destroying the old
balljoint and drilling out the rivets. It'll take me 1hr per side for
the upper ball joint. The lower ones are much easier, I cut the out
part of the balljoints and use a C-clamp type press to press it out and
in, 45 mins. a side.

So for those of you even thinking of doing a total front suspension
rework on your 116 cars, including both upper and lower A-arm bushings,
all ball joints and lowering the front end, it will cost you A LOT OF
MONEY, no less than $600 I would think. But doing it yourself could be
frustrating and trying. It helps to ask for a way to best approach the
problem before doing it because I promise you it will be most
frustrating, especially with 20 year old 116 cars which have seized
parts. I was lucky that my wife wanted to help me out hehe 8-).

The reward is that handling and ride is much improved. So before anyone
jumps to the conclusion that the shocks are shot, I suggest inspecting
the balljoints and a-arm bushings.

Subject: LOWER BALL JOINT


I've just changed the lower ball joint on one of my six 75s, a job I've done
several times before.
     This time the ball joint is different, the threaded section is larger so
the old nut will not fit. Also there is no longer a hole for the split pin.
I'm told this is the new improved design!

 I rang my dealer who checked his stock and all were the same. I ordered two
new nuts only to find that the old castellated nuts came and didn't fit. The
new size appears to be 14mm the nut should now be a nylock nut. I still
haven't managed to get the correct nut I'm using two nuts at the moment
    So if you are planning a balljoint change make sure you've got the correct
nuts before you start.

BTW the new retainer rings can be installed using a "6-lug axle nut
socket"
used for the Dana 70
series axle. You can get one of these sockets from AutoZone for about
$20,
#OEM 27046.
Unfortunately, I couldn't this tool to remove the old retainer. That one
had
to be cut out with a

Subject: Re: Beat It

Biba,

Do you have the old one (rear trunion/gearbox bush) out yet?
I've done
two so far, and they are harder to get out than to get in.

To remove: Support the tranny with a jack, remove bolt
securing
transaxle to chassis. Remove parking brake cable from passenger side
brake caliper. Lower transaxle to allow access to bushing... be
careful not to damage flexible brake hose. It should be long enough to
allow access to the bushing.

Now you need to attack the bushing which probably now has the
consistancy
of tar. I used a big drill bit, and turned it into swiss cheese. You
should be able to tear the center out of it. Using a utility knife, or
some other method clear away some of the rubber exposing the steel shell
of the bushing (it's sandwiched in between the ribbed rubber/plastic
outside, and the inner rubber bush.) Take a cold chisel, get it under
the lip of the shell, and hammer it up towards the center of the
bushing. This will cause it to tear away from the transaxle casting,
and eventually you can pull it out. You can also try a hacksaw, but
I'm better with hammers. (If you have a pnuematic hammer go for it...)

To install: First clean up the hole... I used a small SS
brush on my
die grinder to remove all the left over bits of rubber. The hole
should be nice and clean. I then took a little dish soap, and water to
help lubricate the new bushing. Squeeze the new bushing in with a
C-Clamp and some scrap wood to protect the bushing and transaxle. Take
care to make sure it goes in straight... Make final adjustments with
hammer.

Should probably take less than 2 hours if you have some air
tools, and
don't have any catastrophes along the way.

For the front bushing (I assume you mean the deDion bush...) put
your OEM
bush away, and call AlfaBill and order a polyurethane one. It comes in
two pieces and you just press 'em in with your hand. Plus the
polyurethane is theoretically better for handling anyway. Installing
the OEM dedion bush (in situ) is a real nut buster, and requires some
creative pressing, hammering, swearing, etc.

Tip: To remove watts link bushes, sway bar bushes etc... Remove from
car. Use propane torch to gently heat the metal surrounding the bush.
As the plastic shell melts they will slide right out. Do this
outside cause the plastic will smoke/burn. You don't need to get the
metal very hot, so you don't have to worry about changing it's
mechancial characteristics.

Subject: [alfa] Rear wheel bearing replacement 101 (transaxle cars)

David -

No I haven't written up the procedure before, but for your benefit and
others here you go. Please note that it has been awhile since I have done
one of these so I'm going from memory.

Without the essential tools, primarily the two or three special tools (more
on that in a moment), some assorted air tools (very large air impact wrench
for one), and oxy-acetylene torches this would be best left to a specialist
who has this stuff. Otherwise, if you are comfortable working on your alfa
and have (or have access to the proper tools) go for it. It is not rocket
science, nor does it involve calculus of any kind.

There are two different types of retainers used on the bearings. One was
used on the Alfettas, and the other on the later cars. You will need the
proper ring nut tool for your application, and a pair of replacement
retainers as they will most likely get destroyed during removal. The
retainers are interchangeable as long as you have the proper tool to install
the replacement. Lastly, I am pretty sure that the early retainers are NLA
anyway, so it is all kind of academic, other than the fact that if you have
an early car with the original retainers, you will need both ring nut
wrenches.

I strongly suggest putting the replacement bearings in the freezer the night
before. This will help them go in a little easier.

1) Remove cotter pin and loosen the nut that holds the stub axle to the hub,
access is through the hole in the middle of the wheel. This is very tight,
use a very large breaker bar or pipe.

2) Raise car, and support securely. All the usual safety disclaimers apply.

3) remove rear wheels

4) Unbolt half-shaft from stub axle. Be sure to clean the insides of the
allen head bolts with a pick and tap the key in ALL THE WAY. An air wrench
is usually needed to remove this easily. I think you will have enough room
if you wire the half-shaft up and out of the way, otherwise you might need
to remove it completely. Sorry can't recall for sure.

5) using a large BRASS punch, tap the stub axle out of the hub and bearing.
Leave the nut on the end of the shaft to protect the shaft. There are also
tools that can be used to do this, if you have something by all means use
it.

6) using a slide hammer, remove the hub from bearing. It will probably take
some effort but will come out.

Note: The order of the last two steps might be reversed, can't recall for
sure, but I think I have it right.

7) Most likely the outer race will be stuck to the hub. To remove, place a
large bearing separator on the assembly, heat the race until nice and warm,
and press the race off. You could also cut it off with a die grinder of some
sort, but be careful not to damage the shaft on the hub.

8) Now the fun really begins. First you need to remove the retainer, these
are torqued ungodly tight and staked in place. Add to this years of
corrosion (unless the last guy who replaced them was kind enough to use
anti-seize) and they are a PITA to remove. On a really good day, a 3/4" air
impact wrench with the air pressure cranked way up will be enough to remove
them.

On a not so good day, you will need to soak them in penetrating oil, heat
until glowing and then remove them.

On a really bad day, you will have to cut them out. It can be done without
damaging the threads by cutting in the groove that is provided for staking
them in place.

Also, remember that one side LH thread, and the other RH thread. This just
adds to the confusion.

9) You are now ready to remove the bearing(s). For this you will need either
the special Alfa tool, or a generic wheel bearing service kit of which there
are many on the market today. Assemble the tool in place, there is a slug
that fits the ID of the bearing that goes on the inside, the cup goes on the
outside and the pressure screw goes through the whole thing. Crank it down.

The bearing probably won't move. At this point, if the car has ABS remove
the sensor. Get out the oxy-acetylene torches again, this time with a very
large heating tip (you do have one of those right?) Start heating up the
housing. Move the torch in a large area to try to warm it somewhat
uniformly. Every so often crank the screw and/or hit the end of the screw
with a large hammer. Eventually it will start to move.

10) After everything cools down, clean up the inside of the housing and the
threads as best you can.

11) To install the new bearing, remove it from the freezer, and working
quickly, assemble it and the tool and use the tool to press it into the
housing. There is another slug that fits the OD (this is very important
otherwise you will damage the bearing, always press bearings in by the OD),
and either another or the cup (depending on what type of tool you are using)
that goes against the back of the housing, The screw goes through it all and
is used to draw it in.

12) Install retainer, torque to spec, and stake in place (like it is really
going to go anywhere?)

13) Use the threads on the stub axle to draw the stub axle into the hub, do
not tighten fully at this point.

13) reassemble everything else.

14) with the wheels back on and the car on the ground torque the center nut
to spec and install the cotter pin.

That's about it. With the right tools it is not that hard provided
everything comes apart as it is supposed to. It's when things are rusty and
corroded that it gets more difficult.

HTH,

Jeff -

Give me a couple of days to look up the part numbers, but I can tell you beforehand that I got all this stuff from Speedway Engineering.  Our chassis uses a 33" bar.  I ordered aluminum straight arms, heated them up and bent them to shape.  I've got a 3/16", 1/4" , and 5/16" wall thickness bars.  The 5/16" bar is my current favorite, and it almost seems like I could go one stiffer.

There's a picture of this setup on my car in the photos section of the Alfa Racing site.

I don't remember the prices exactly, but I believe one torsion bar and two aluminum arms were much cheaper than a Shankle sway bar.

Hi Andrew-

Here's the scoop-

Speedway Engineering is where you get the bars and the aluminum arms, but it looks like you've already figured that out.

The arms will have to be bent to match your OEM sway bar, which can be done with an oxy/acetylene torch.  If you don't have the resources for this, have the arms drop-shipped to me.  I'm doing this for Al Mitchell's GTV-6 E Production car right now.  My shipping address is below.

The tubes that you should order are 33" in length, and I would start with a 3/16" wall tube, part # 608-188-33.  If you're so inclined, I would order another bar that is stiffer to give yourself some adjustment options.  The 1/4" wall tube is part # 608-250-33.  They're $82.00 each.  If you're racing in the rain, having the 1/8" wall tube would be handy as well.  Ahhh racing.....

You should replace your end links with rod ends.  There's a simple way to do this with metric rod ends.  Al Mitchell knows the source for these, and they're really not expensive.  They're important because they will remove the compliance of the rubber bushings in the OEM end links, and will provide a way to set the preload of the sway bar by adjusting the length of the rod ends.  You can use a set of 1/2" rod ends and modify the diameter of the stud coming off of the lower A arm, but this is more hassle than it's worth when comparing it to the added expense of ordering metric rod ends.
