Re: '90 200TQW wisdom sought



OK granted my car is somewhat different (I have an '87 QSW) but we both have
Quattros, so maybe this will apply..
    My car does the same clunk, and I originally thought it was the driveshaft
center support bearing. However, I recently jacked up one of my rear wheels with the
other three on the ground and peered under the car while I turned the rear wheel. I
was able to turn in about 3/16 of a turn without any of the other wheels turning at
all, with the car in gear. Looking under the car to see what CV shafts/driveshafts,
etc, are turning, I was able to determine that there is a fair amount of slop in
both the rear diff and the center diff/tranny, especially the latter. I've checked
the trans mount, rear diff mount, and center bearing, and all are good, so I've come
to the conclusion that I just have that much slop in my diffs. Oh well I guess
that's what you get with a 170K mile car. Anyone else have experience with this?
(for those of you who don't know, my drivetrain is virtually identical to the 4000Q
drivetrain... the only difference is in gearing and the rear suspension).
