    Default Clunking sound... bad shocks?

    So i've been chasing down a clunking sound in the rear end the past few months. It's not u joints, it's not coming from the diff. It's not the control arm bushings. It's real bad when I first start off in the morning, but seems to get quite a bit quieter after the jeep's warmed up/been driving around for a bit. It really seems to be suspension related.. get the bump sound every time I hit a bump, small or large. Rear track bar is good and tight, rear sway mounts are good and that is tight. The shocks are only a year old, but one of my rears was banged up a bit. Probably going to pull them off this weekend and drive around to see if it goes away. Just looking for more ideas.

    Any other suggestions?

    Whoever installed the shocks in my XJ, didn't put the sleeve in the bushing.

    They rattle and/or bump with every little crack in the road.

    With the shocks, you can either reach in and try and wiggle them, or rock the rig from side to side.

    Either method should let you hear the 'clunk' if it's the shocks.

    My left front sway bar bushing broke and it made a clunking noise. I had to look really close to see that it was actually broken inside the rubber and grabbed it and pulled on it.

    Whatever it is, good luck.

    Sounds like the stupid bar pins to me. Look at the upper rear shock mounts. The shock bushings are hour glass shaped and sometimes they will slip out to one side of the eye they fit in. The clunking noise results from the shock eye making contact with the bar pins. The fix is to pull the shocks, squeeze the bushing back in where it is supposed to be OR buy a bar pin eliminator kit. Also check your lower front shock mounts. They have the same bar pin set up and will cause clunking too.
    This of course applies to TJs and XJs.

    Yeah.... I've started finding a bunch of threads about the bar pins... they're at the top of the list of things to check.

    The bar pin eliminators are nice, but some require the metal sleeve inside the shock bushing. Mine are missing, that's why mine clunks

    bar pin eliminators did the trick.... no more clunks, and no more messing with those stupid upper shock bolts.
