Re: Rear end lube and noise

Ok from what I understand, there are only two reasons a rearend will moan, incorrect gear spacing(worn gears over the years) Or the bearings are worn and have slop.
Your probelm sounds like to me the gears are just worn enough to let it moan.Does you diff. Leak out of the front seal. Tha might lead to another problem. But actually sounds like it might be time for a rebuild or another diff.
Putting in a thicker gear oil, might quiet down the moaning but really I believe it will be just covering up the problem. Just my $ .02
