Re: E-30 rearend noise

["Allan Williams" <allanw@xxxxxxxxxx>]

I think all manual trans 325s have a sort of whine in the diff...it is
always constant, but varies with speed. Our 91 with 92,000Kms does it, and
so does the '88 with 160,000Kms we tested before the one we brought. I don't
think the autos did it though.

Can anybody say for sure???
