Got into my daughter's car 2005 Audi A4 Quattro for the first time in a few months and noticed a thumping/grinding sound coming from the rear when driving. It progresses and slows in conjuction with the speed of the car. Tires are fairly new (one year). No loose lugs. No movement from rods. No leakage in rear differential. 94,000 miles. Any other thoughts?

 

"I don't see nuthin' wrong with a little thump and grind"

on a serious note, check the bearings

 

Bearings it was. Along with $1300 to take care of. Thanks

 

Holy ***** you paid $1300 for bearings?!!?

 

hehe....i guess i missed the part where it needed a fuel pressure sensor too. There was a time when I did all that myself...now I just don't have the time.

 

Still... thats why i do everything myself. So much cheaper and you may learn a thing or two along the way.
