Clunking noise from rear right

It comes from the rear right of the jeep upon any type of flexing. Most noticeable when going up a driveway. Leaving or driving up from driveway pulling in on an angle.

All of the u-joints are fine. I was thinking either the rear right hub, maybe something loose with the suspension, shock or possibly the leafs rubbing against eachother.

The Jeep sat for a while with the previous owner, maybe 1-2 years.

A thorough visual check will reveal quite a bit. I'm guessing the trackbar mount.

Pics?

Will do an extensive one tomorrow. I just crawled under and checked to see if anything was loose. Hoping it is the trackbar mount, then i can cut them off

For me, I had extensive creaking / clanking because both rear corner body mounts had punched through. Fixed, life is quiet.

Happy Hunting,

FWIW

Finally got around to checking the rear out and this was all that I found. The 2 body mounts under the passenger door have slipped or the bottom rubber mount released. Not sure if this is whats causing it but everything is just fine. U joints, U bolts, springs, brake drums, hubs, wheel nuts, exhaust doesn't bang into anything, gas tank cover isn't loose, shocks and shock mounts are fine. I did however find that the rubber suspension blocks/bumpers are missing on both sides.

It sounds like metal shifting together... Kind of like if a leaf spring was broken and sliding, popping over and over.

I had the exact same scenario. For me it was the track bar. I replaced the bushings and it went away. However Since then I've yanked em both and they now collect dust under my bench. Your body mount doesn't look so hot, it could be possible that's the culprit.

When you checked the track bar was it loose when you tried to move it?

Mine did the same thing when the Jeep flexed a little, like leaving the driveway and such. Turns out that one of the body mounts for the rear leaf spring was wallowed out, allowing the spring bolt, hence the spring eye, to shift up and down. I've been meaning to weld some washers or something in there to make it round again, but never got around to it. Right now it's just extra tight which helped.

What is the eye of the leaf spring again? I'm not sure maybe the shackle is grinding something. Those 2 body mounts don't look good but then again my other jeep had none in the rear lol
