Could be a uni, or suffering backlash in the diff like mine was.
I'll move this to the driveline section.

Check all the bushes in the rear suspension, and position & tightness of the U bolts. It helps the ride to apply Moly grease to the slip pads at the end of each leaf of the rear springs, ride quality that is.
Also check the pinion bearing by seeing if you can move it up & down with your hands, & look at the unijoints to.
Another one to look at is the slip-yoke bush at the rear of the auto.
the are renowned for flogging out. if its stuffed it will move up & down about 3 to 4mm at the front uni end or about 1mm or more at the oilseal.

That doesn't mean your diff is stuffed. I'd be surprised if you can't do that in any auto.
