Re: Rearend or rear suspension clunk/creak

Dealer replaced my load-leveling rear shocks about 4000 miles ago, at about 9000 miles (the noise started at about 5000 miles and 6 months after delivery). They also replaced the end-of travel absorbers and the bushings on my rear sway bar. The noise has not returned.

I have all the warranty repair invoice info detailed in post #41 and the other forum treads.

My new shocks have the same AB part code as the original shocks, so I did not get the redesigned AC units.

Re: Rearend or rear suspension clunk/creak

There still hasn't been a TSB released?

I think the cold makes the sound go away or suppresses it. I've had mine replaced about 5k miles ago and it started coming back in the fall, but since it's got cold it's gone. Except for a few of the warmer days it's noticeable. I bet once it gets warm out again a lot more folks will have the issue again.

Re: Rearend or rear suspension clunk/creak

Already 5 days in the service area and still no phone call from the dealer.
Let see what they come up this time.

Funny, mine was the opposite...I noticed it more as it got colder.

Re: Rearend or rear suspension clunk/creak

Ditto, my noise showed up when the weather got colder (and all the salt and chemicals on the roads). I am reasonably optimistic, since I expected the noise to return this winter - which it has not yet.

Again, note that on mine the dealer replaced the end of travel absorbers AND removed the rear sway bar - replacing the bushings and reinstalling.

I am not aware either of these has been done on any of the other forum poster's rear LL shock replacements.

On mine, it appeared that the root cause of the noise was the shroud over the top 1/2 of the shock was very "warped" on the original shocks. On the replacements, it has retained it's shape. The noise appeared to be caused by the warped shroud rubbing on the metal of the shock. When I laid under the GC and had someone push/pull (on the tow bar insert), the noise was readily heard - until I reached up and grabbed on the shroud and the noise went away.

Now that it's above freezing I can't even hear mine anymore...I may cancel my appointment until it gets worse.

Re: Rearend or rear suspension clunk/creak

I'm just hoping Jeep releases a TSB for this. Yesterday it was 76 and the clunk could be heard over my music. On cooler days I hear it, but its not as bad, maybe a heat expansion issue?

Re: Rearend or rear suspension clunk/creak

Since no one has called me from the service dept. I went and visit them today.
The story is that they are waiting on a new shock and shock mount that supposedly supersedes the # 68069680AC version.
Let's hope this finally fix the problem.

Wow, I applaud your patience. My vehicle is in for the 4th day in roughly 14mo and I am not happy about it at all. Our last 6 new vehicles might have been in the shop for 4 days if I add up all the service time and add it all together!
