Rear End Noise 8 3/4

If it just recently started whining it very well could be the inner pinion bearing going south. On acceleration the inner (large) pinion bearing is taking most of the load. Regardless if it's the ring & pinion or bearings it needs to be opened up.

I would also agree that a 4x4/truck repair place is your best bet for the repair if you don't have a differential only repair shop.
