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

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.

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).

Check for play in the yoke shafts going into the rear diff.   IF there is too much play in and out, the wear will create stress in the posi unit and bad noises will ensue.  Fluid won't help this one.   I have a lot a rear end noise, and so does my car.   The yoke shafts are just sitting here waiting on me.
