Anyone have a diff they pulled out from the no core required ratio change deal? We are running low on cores for builds.

Peterpan BMW in San Mateo, CA will replace my diff two week from now. Maybe you can talk to them if you want it. Mine's whinning on higher speeds, nothing major tho. They claim that it's normal for it to whine, but some might be quieter...i dunno, i'll let them try.

Thanks, but they aren't allowed to do that. To get warranty money back from BMW, they have to return a diff.

Are you rebuilding diffs with the 3.91 or 4.10 ratio?

Both.
