Noise from rear on a pit road

Hello,

I have a noise from rear, when my 02 Grand Cherokee 2.7 crd is on a pit road.
The shock absorbers are good. Everythink seems ok.
What would be the reason?

Is is a 'clunk' sound? Check to make sure the shock bolts are tight. I think the upper nut is 80 ft/lbs and the lower is 85. When I installed new shocks, I thought they were tight, but it made a clunking sound.

Push the body from side to side over the rear end of your WJ. Get it rocking pretty good and see if you hear a clunk. If you do, most likely, the upper A-Arm ball joint is shot.

X10... it’s a good chance its the Rear Upper Control A Arm and Ball-Joint..
I was having the same “Clunk” noise from the rear when going over bumps until I replaced both parts.

i'm going through my suspension, and found the a-arm, and the bushings to be suspect. since it's all right there, i'm just ordering a complete set-up from @Kolak , to go along with the rest of the suspension/lift upgrade. i would get a random repeating clunk on washboard tracks, but i couldn't pinpoint the source. pulling off the a-arm, i can see the end bushings are toast, and the ball joint on top of the pumpkin is gone as well.

Sounds good...l’m keeping my stock height, but I changed out all the Rear Suspension parts from @Kolak .

And, just because my WJ is 20 years old I’m also changing out all the Front Suspension and most Steering parts from @Kolak

Same here. I'm replacing all the remaining steering and suspension parts soon. I figure with 16 years and 283K miles, why not. Should drive better.
