When i go down a driveway while truning right, i hear a loud clunk from the right rear side, i also get a sense that something moving along with the clunk. i was thinking springs...98 jimmy sle, 4.3 , 4x4 auto.X7D2ED1C

Sounds like a bad U joint in the drive shaft or axle CV.joint .
When you go over a bump or hole the wheels move up and down the drive shafts and axles have to move along with them or they would bind and break something in the drive train .
When they ware they tend to clunk going in gear power on they get tight power off there loose that's why it makes a noise .

Quick Guide to Diagnosing Differential & Driveline Noises ...

bolt may have come out or grommet is shot, if you crawl under with a flashlight and have somebody lean on the fender and push up and down you may be able to see what it is, don't get squished however

If the issue is persistent while driving on smooth road, your issue may be related to a bad wheel bearing. If the issue is only persistent while hitting light bumps its probably more related to a bad suspension bushing or component like a ball joint.

I'd inspect both sides and try to detrmine if you see any differences in the sides. If a boot or something along those lines are torn that could be the culprit.

I'd also suggest raising the rear of the vehicle and attempting to move the rear wheels up and down or back and forth (please use jack stands and have someone with you while doing so) to see if the wheels move. That may allow for some clunk that you can maybe see/hear.

check for worn loose "u" joints . check for loose drive shaft pinion. Check for worn suspension rubbers on rear end allowing the arms to move up and down

Check your top shock absorber and/or strut mounts, they may have been hammered by the many bumps and stripped out the mounting hardware on top just an eighth of an inch which will cause super loud bangs as that side wobbles up and down and hits into the Body Metal. These can get dangerous if left loose at all, my old boss said his Taurus would change lanes by itself at 120 Km/hr in the rain!

you don`t say if this is a 4x4 truck.if it is it could be the Ujoints/halfshaft joints on the side thats making the noise.another thing to have checked is the upper and lower control arm bushings for being worn out causing the noise.just suggestions.

Could be rear brake locking up,cars arent used to going backwards or hand brake sticking on . Would look there first.

universal joints clunk,is it in the rear end then maybe it is the rear end.you kinda need to be more specific if this information doesn't help
