If you've removed the isolators over the springs, that'll be your problem. I took mine out and wrapped the top coil with heater hose just to get a better stance with my Hotchkis springs. They rattle on bumps, so I think I'm going to have to wrap them with a slightly thinker hose.

Does it squirm or bang on axle travel, or just make
"body noise"? Could be something as dumb simple
as the jack or spare being loose.
If you don't feel it as squirrely handling then it may
be exhaust banging against some part of the rear
body / undercarriage.
Put it in park with the parking brake on and push the
*** end side-side; anything but tire squirm indicates
Panhard mounts / adjuster (if you have an adjustable).
The Panhard bolt has a sloppy fit in the mount and if
it isn't hard tight it will make a metal-metal sound and
be a bit more sloppy.
Now bounce it forward/back; any clunks or shift is most
likely LCAs (maybe TA too if really loose).
Last, bounce it up/down, checking for shocks being loose,
upper or lower mounts, springs shifting, etc.
None of these -should- make a sound, but if you can find
which axis is the noisemaker that will help you narrow
down the source.
If it's oddball non-suspension stuff, being out back may
also help you get another angle on where it s.
