So, I've stfa for a while and I think that i've got this narrowed down but I'd appreciate any help from the resident experts here...

2001.5 B5 S4 - 71K miles

New tires, alignment is done and good. Everything was smooth and quiet for a while - 1000 miles.

About a month ago I noticed a cabin "buzz" eminating from the rear (I think). I checked for anything loose in the trunk, exhaust, license plate, etc. Nothing. The "buzz" is most noticable on city streets from about 20 - 50 mph. On the freeway I don't hear it. The radio can also drown it out.

Lately (last week or so) the "buzz" is more noticable and there seems to be a "growl" from the rear end - most noticable while slowing down. The brakes are fine all the way around.

The last clue I have is that when I steer slightly left (lane change or lane correction, the noise disappears for a second.

It's REALLY annoying.

I'm thinking wheel bearing or maybe CV joint...

Any ideas would be greatly appreciated!

TIA

If it goes away when you steer it is most likely a rear wheel bearing. Also, if it keeps getting worse and more annoying like mine did. At least you asked the forum, I took mine in thinking that the tires were severely cupped and was lucky the technician knew his stuff. He turned me away gently and I got the bearing fixed instead. Good luck.

2nd. sounds like a wheel bearing to me

Both of you were correct. It was indeed the rear wheel bearing (left) I had both replaced. All better now!

Thanks!
