I've searched here and it seems no one has had the problem I'm having. The rear end whines and it's real bad at 60 mph or so. It is not tire noise. The whine goes away at higher speeds and is not there at 50 or slower. It has gotten worse lately. My coupe has 37k miles on it. Any suggestions or common problems you all know about? I even changed the rear end fluid but that didn't help. Thanks guys for your help.
