'92 325is coupe - loud "rubbing" noise in area of LR tire - only on rt. turns

1992 325is coupe, 5-speed, w/114k miles. I just bought this little black beauty and she came w/ full maintenance records going back to first owner. Always maintained at same San Francisco garage. A week ago I replaced the exhaust, from the cat - back, at a reputable BMW shop. Before that was done, the exhaust sound was loud, but I don't think it was loud enough to drowned out the noise I'm hearing now. Meaning I strongly suspect that something happened during the muffler replacement that caused the current problem. But I'm not certain.

What I'm hearing is a noise that almost sounds like the left rear tire is rubbing on the wheel well when I make a right turn, but I've jacked up that corner and looked closely, and I'm pretty sure that's not it. I see no evidence of anything rubbing on inside of tire, wheel well, or shock. Right turn can be very slight, or 90 degrees, but the sound only happens on rt. turns and absolutely nothing weird happens on left turns (no noise at all. If I listen real hard and sort of "gently swerve" to the right at about 50-60 mph, the sound almost sounds like it's coming from directly under the center console, and I can almost feel something rubbing or "clunking.". Rubbing noise is probably related to speed of travel, meaning the "frequency" of the rubbing is lower at lower speeds, but it's still there.

I've also tried to make right turns while coasting (either in neutral, or w/ the clutch depressed), but I don't think the sound is affected.

CV joint?
Thx in advance for any help.

Rubbing noise at LR only on rt. turns.

Sev03,
Thanks very much for responding to my post.
The bearings you're talking about - you mean the wheel bearings?
Meaning that your mechanic said either one, or both, of the rear wheel bearings need 2 be replaced?

Thanks again.
Dennis

'92 E36 rubbing noise on rt. turns.

Carl,
Thanks for your feedback, but i really wouldn't describe it as "humming." It's really more of a 'rubbing' noise; I swear it initially sounde like my LR tire was lightly rubbing on the inside of the wheel well, but i can find no physical evidence of that.
Another possible clue I discovered while riding in back seat while my wife drove - again, only on right turns - I can actually feel a slight rubbing (like a bump-bump-bump) on the floorboard behind the driver. Left side of car - rt. turns only (body is leaning to the left); nothing on left turns.
Bad LR wheel bearing?

Thx again.

Rubbing noise on rt. turns only

Is it likely that bad shocks (especially the left rear one) would contribute to a noise like this? FWIW, the LR shock definitely makes an annoying squeeky-squeeky noise almost always.

Rubbing noise

I also have a rubbing/ thumping noise from under the center console area... it started it on right hand turns... now it does it going straight down the road too... could it be the exhaust rubbing on the drive line? worn bushings? i'm stumped... help please.
