I'm not sure but jack up the rear tire and spin it. If you hear noise then
it is probably a wheel bearing. If not I was told by a list member to go to
a supermarket parking lot and drive in tight circles and your CV joint will
rumble if it is that.

> I have an '88 Westy with 150,00 miles and I'm hearing a noise coming from
the right rear. The noise changes pitch with speed, and is louder under
accelleration than when coasting - though it is still rather quiet. (e.g.
you can't really hear it with the radio on.)

diagnose which is causing the problem?
