86 325es. Groan when speed gets above 35 to 45 MPH. Hear it when going straight ahead or turning right. Disappears when turning left at that speed. Suspect something on left side of car.

Wheel bearing?

Axle shaft?

It's the wheel bearing, part cost like $40 but I think they quoted $500 to fix mine... I say do it yourself.

How can I tell which wheel is the problem? Should be left side, but front or back. Can't tell by listening.

it's pretty easy to do your self if you have the right tools, i couldn't find the part for less then 130 new, so i had to get a used one. If it dissapears when you turn left, then it is definalty the left side and i would say it's the front, those are uasully the only ones that ever go.

Lifted both wheels off on jacks. Front seemed okay. No noticeable problems. Left back was almost impossible to turn without tire on. With tire on it was very difficult to turn.

Pulled the left rear brake rotor off to see if emergency brake was hanging, same difficulty in turning the wheel with the rotor removed. Is this normal, or does it appear that I have found the source of the problem?

when there is no weight on the wheels it will seem like there is no problem. hence the sound dissapearing at turns. the back wheels are uassly harder to turn, do to the fact of your not just turning the wheel, but the diff and drivesaft too, and if in a LSD the other tire. go around spinning all the wheels with the car in the air and listen for one that sounds different. it will sound like a dry wheel bearing. you can't tell by just looking at them becasue they are all one sealed unit attached to the hub
