Grinding noise when turning left

Generally, a bearing noise when turning left means the right wheel bearing =
is bad and vice versa.  I would recommend waiting for it to progress until =
you can at least hear it with the bad wheel jacked up and turned by hand.  =
I am starting to believe that front wheel bearing problems are climate rela=
ted.  I have been in California now 10 years and have not changed a front w=
heel bearing but, in the East I averaged about one bad bearing a year for m=
y 3 Audi's.  I thought axle boots would do better here also but that is not=
 the case.

Interesting. I've had a similar noise that I've noticed since I got
my '91 200 20V tq avant in January. The car makes grinding airplane
(sometimes helicoptor like) noise especially when turning/loaded to the
left, a tad on the straights and noise dissapears turning right. I
have assumed that is is a wheel bearing, and am prepping for major
surgery.

If someone finds there is some different quirk happening with these
cars, I'd appreciate knowing. I have never had a wheel bearing go at
the early age of 107K miles. Of course everything looks fine with no
CV boot damage, and of course you can't tell a wheel bearing is bad by
looking at it - 'cept maybe after removal.

Pat,

I've noticed the same in my car for some time as well, and the source
has baffled me. It sounds a lot like a CV, but the boot is fine. And,
it does only happen at or very near full lock...going left.

I can definetely tell it's from the front left wheel, but not sure
what's causing it. Somebody had suggested maybe a bad ball joint,
allowing excess movement, but I imagine if that was the case I'd hear
going both directions, and I'd have some tracking issues...not the case.

I too am confused on this one.
