Default Re: Control arms are one of those annoying issues...

From what I gather the CA's are Aluminum correct?
What do they use as a bushing material? Like for
example my Vette has Aluminum Control Arms front
and back. And both end of the car have Polyurethane
bushings from the factory (Z51 Road Race Suspension
Package).

What does Audi use as a bushing material? I went
to school for machining as did most of my friends
so getting a better bushing machined and pressed
into the stock control arms wouldn't be a problem
if it would correct the wear problem.

And working on the car isn't a problem either. I
can handle everything except for the alignment
myself.

Default Well I am glad to hear that!

Turning,

I for one am glad you are here And in the
future I am going to use the search feature just
to avoid being flamed by the "other" people on
the forum.

I understand what you mean about it not being a
normal wear item and I am glad to hear that not
everyone has had problems with the control arms.

I can say from being a Corvette enthusiast and
after owning 4 of them so far, we have our own
weak points and flaws too. I have never come
across a car that didn't have some sort of flaw it
happens but it sure doesn't disuade me in the least.

I may even go as far as to pick up a spare set of
control arms just to study and then design a better
bushing system for them if it is possible. Having
access to all of the required equipment and having
a background in machining and CAD helps plus all
of my friends are machinists for a living.

Default Low Tek suspension photos...

For low tech it looks fairly complex. But it
doesn't have AWD though...

Default Not bad for a Stratus. Must be cool to see the speedo

pegged. Probably never peg the A4's 160MPH speedo :-(

Default

I'd be inclined to say rubber. The arms are aluminum.

Default From everything I have researched the bushings are what go bad on the arms, and not the arms

themselves. The bushings are rubber, and used for luxury ride compliance. There are a few places that sell poly bushings for our cars, but not every bushing is made. You still must replace (the Lower ones I belive) some of them from time to time.

I currently sit at 84K and I have no real problems.

Default If you can come up with a fix....

I'm sure there's some definite profit to be made. At least you understand no car is perfect. The A4 has its flaws, but it's still a great car. I'm still and Audi enthusiast even though I don't presently own one.

Default It's no Vette at 130 lets put it that way..

My Stratus is a hand full at full speed. The C5
at 130 is almost like a Caddy at 55mph.. It's just
so smooth and *quiet* too... The Vette doesn't
start to get light right up untill the top speed
which is drag/HP limited to about 179/180 MPH in
stock form. The funny thing about the Vette is
that top speed is in 5th gear but if you tack on
about 150 more horse then you can reach top speed
in 6th gear which at 450-500 horse runs up around
202-210 MPH (I will NEVER see that...)....

After going that fast 55 must feel like 5....

Default I think that because the bushing go bad...

that causes the control arm itself to wear and go bad.
