THE REAR END MAKES A WHINNING NOISE WHEN DRIVING, BUT STOPS WHEN YOU LET OFF THE GAS. I REBUILT THE REAR END AND THIS DID NOT FIX THE PROBLEM WHAT ELSE COULD BE MAKING THIS NOISE IT IS GETTING VERY LOUD[/quote:6227445101]

To much backlash.
.007-.010 mesured off the ring gear with a dial indicator.

When you change out bearings and such....you have to re-shim for the correct lash while keeping a good gear patern with the ring and pinion.....
