Took the diff cover off to replace bushing. Bushing is deformed and causing diff housing up/down movement.
I replaced it with new Powerflex urethane type bushing.
I am amazed. No more clunking in the rear.
Although the diff is bolted to the subframe, the sheet metal is so thin it is flexing as I raised the diff with a floor jack while aligning the bushing to the hole.
One problem solved.
Subframe bushing next. __________________
