Need some input

The problem I'm having is on my 03 auto I'm hearing a clunk in the rear when I'm at low speeds giving light throttle like letting of the throttle the giving moderate to light throttle I sometimes hear a clunk and only sometimes most of the time its fine starting to bother me . well today we serviced the tranny pulled the drive shaft checked the ujoints there good no binding.. then took it for a ride all was good when I parked I decided to check the rear calipers the drivers side rattles pretty easily with my hand the left side nice and tight. But I can still reproduce the clunk at low speeds like going over a speed bump then applying throttle then a clunk but not all the time. So I was thinking maybe the rear caliper is clunking or the lower control arms there stock. Any opinion will be greatly appreciated.

I'd check the lower control arms , they tend to give out after a while.. wear and tear.

Bushings will be busted , also check the differential bushings on top of the pumpkin.

OK so today I looked at upper and lower control arms. Lower control arm bushings look good the upper control arm bushings had some cracks on the the connection to the diff so are those bad and causing the clunk there not busted just little crack's so it doesn't seem enough to make it clunk any other ideas or am I wrong

I've had numerous issues with control arms , that's really the only clunking that happens .. and it's horrible.
I'd take the upper ones out and check them in front of your face to really know and it'll get you a better look at your diff bushings.

I've went through 2 pairs of oem , and 4 pairs of sve control arms before I actually bought extreme ones.

So you think its my upper control arms also when we had the car on jack stands running and in gear we saw a lot of wheel hop while the car was running is that an indication of bad upper control arms.

Adding anything other than OEM upper control arms can be dangerous. For one you can rip the chassis side mount out of the frame because you don't have give there anymore. And two there is this dangerous condition called snap oversteer.
Ask soccerlover or Scotty and they will tell you the same thing. Save your money for a pan hard bar and torque arm if you really want performance. If you want the clunking to go away get a new set of bushings or buy new OEM uppers.
