Rear Diff R&P Carrier?

[xmarkx]

the tranny shop I just had work done at told me he wouldn't rebuild my diff's with Richmond gears. he told me he would only do it with Yukons or none at all. I was shocked because Richmond is a well known name. he told me that he's had moringest related issues in recent years (on his own vehicles) to the point where he doesn't trust them anymore...
