Does it make this noise every time you back up?
Has you checked the front diff mount bushing?

That was going to be my next shot Joel,it cant be the E-Brakes the P.O. removed them,and I havent gotten around to puttin new ones on,all the hardware is gone too,the half-shaft u-joints seem good and tightI replaced 3 of them a couple of years ago,haven't checked the drive shaft ones yet,keep them ideas comin,but make them inexpensive please. Isn't that an oximoron inexpensive and Corvette

when is the last time the rear diff was serviced with fluid it could be the disks in the differential mine did funny things when driven a long ways serviced with proper additive drove around in circles rt and left smooth rear after that.

O
I've seen (heard) more than one fixed, including mine, after chasing the noise with a simple change-out/clean out of rear end fluid (BAD MICKI) and adding the bottle of posi- fluid. Find the good stuff @ Auto Zone (at least 2 years ago) in the back on the top shelf of the additive end cap. Blue and silver or Blue and white as I recall.
Ya can't get much cheaper. And if ya don't want to remove the rear cover and pay for a whole new seal, you can pump it out with a vacuum pump (same one you used on your brakes).
