Re: Clunk!

[Steve Manning <stephenm@ix.netcom.com>]

Al - I have EXACTLY the same problem on a '88 90q...hmmm, other than being
Audi's, what do they have in common?  Because mine's a manual, yours auto;
mine quattro, yours FWD; mine a 90, yours a 200.  I have also checked
engine/tranny/diff mounts and they seem fine.  The clunk sounds kind of like
CV joints, except that it is located further back in the car, and you can
feel something hitting underneath the car.  I was thinking maybe the
driveshaft going to the back of the car, but your car doesn't have one.  I
checked exhaust also.  I can't duplicate it by putting on the brake and
slipping the clutch a little to load up the drivetrain; nothing moves around
that shouldn't.  And it's only when turning right, or occasionally on
initial start.

I'm going to try looking again this weekend; let me know if you find out
anything on your car......SLM
