95 quattro driveline noise

[Joan Kotjarapoglus <jkot+@pitt.edu>]

I purchased a 95 100cs quattro with 50k back in February. Last month I
heard a noise from behind me like it was coming from the driveline.  I am
past the 3 month warranty period so am on my own.  The noise is only there
if I pull out hard on a level surface.  If I am on a steep grade, the
noise is there every time.  I have never had any driveline noise on my 87
5000tq.  Is anyone aware of any peculiar problem with the later audi
quattros which would cause such noise.  George K   jkot@pitt.edu
