Wheel bearings (was Re: Noise from back of S4)
The right, rear wheel bearing on my 2001 S4 was failing
(the quoted guess below was correct). I just had it
replaced. Is it worth preemptively replacing the other
rear bearing? I'm going to be driving a long distance
this summer and if it's going to fail I'd rather replace
it now rather than in the middle of a road trip.
The mechanic said this is a common problem on Audis.

No, don't bother. Your other bearing could go another year or more
(mine did), and any competent mechanic can replace it if you're truly
nervous about letting it go for a couple thousand miles before getting
home.

Re: Wheel bearings (was Re: Noise from back of S4)
Wasn't really a guess. I've heard of the B series chassis having more than
its fair share of bearing failures. I have a 96 S6 with 109000kms and rear
bears are just fine - inspected 6 months ago. Had a front replaced but the
front wheel had taken a whack or big pothole.

its fair share of bearing failures. I have a 96 S6 with 109000kms and rear
bears are just fine - inspected 6 months ago. Had a front replaced but the
front wheel had taken a whack or big pothole.

Re: Wheel bearings (was Re: Noise from back of S4)
Wasn't really a guess. I've heard of the B series chassis having more than
its fair share of bearing failures. I have a 96 S6 with 109000kms and rear
bears are just fine - inspected 6 months ago. Had a front replaced but the
front wheel had taken a whack or big pothole.

I've lost a couple front tires to potholes but it was a rear bearing
that went. You wrote that your bearings were inspected. Is that
possible on an 01 S4? The bearings are supposed to be maintenance
free, meaning they work until they break then they have to be replaced.
