Angry Rear End Whine

I have a very audible rear end whine between 60 and 68 MPH under power...many things have been done to fix the problem, including GMPP work at a Chevy dealer who replaced the ring & pinion, the pinion bearing, and the carrier bearings, to no avail...please help

I have the same problem, except I can here mine from 5mph all the way up. Can the rear ends tighten up, and be "out of lash"?? If the back lash is not enough will the rear whine?? How ahout if there is too much rotational drag??
