Re: Thumping Noise

These are shots in the dark, but possibilities are:

1) CV joints:  check the rubber boots and see fi they're broken.  If
so, you have probalby lost ghe grease and the joint is going.  More
likely one are the outers, but check the ones at the diff. also.

2) Wheel bearing:  first, with the car at rest push firmly in at the top
of the wheel and check for runout.  if this is OK, take car for a run and 
SLOWLY come to a stop (light braking). then feel center of hub shaft.
if this is hotter than the disc, the bearing is going.

Good luck!

 Subject: Thumping Noise
 
 Hi all,
 
        Got a bit of a problem it seems, about three weeks ago a thumping
 noise reared it's ugly head in the Q.  I assumed it was a broken belt in one
 of the cheap tires that was on the front and today bought four new ones.
  Well now that it's much quieter, I know that it was definetly not the
tires.
  The noise becomes noticeable over 40 MPH and gets worse when i take right
 turns and quiets down when i turn left.  It's very loud and I can feel it
 through the pedals!  (This is what I get for not sacrifcing my girlfriend to
 the Audi gods.)  So I'm thinking wheel bearing possibly, but not having much
 experience with Q's I'm probably wrong.  Help!!  TIA
