Hey guys i'm a new member i just got a used 1998 Audi A6 2.8 quattro, rite off the bat i have a problem, when i start driving starting at about 30 MPH i start to hear a grinding/slash wind up type noise (don't know if that makes any sense) the noise is speed sensetive so when the car slows down the noise slows down until i come to a stop. someone has told me it sounds like it could be a bad axle or a wheel bearing. any ideas? thanks for the help in advance guys.

P.S. fyi the car has 154,000 miles

 

Any luck on your issue? my car just started doing this after sitting idle for a few months.

 

Well have you pursued the fact that it could be a wheel bearing or bad axle? I would say the same thing if you asked me. Usually wheel bearings are more of a humming sound; being louder with the severity of the damage, however.

 

Well, I figured out my issue...I forgot to tighten the lug nuts all the way on the wheel. I figured it out today when i went to jack the car up and pull off the wheel. The wheel started pulling inward as the car went up so i figured the stress from that caused my noise. Drove it all the way home and sure enough, that was the issue. Good thing I don't have to take the freeway to work...
