When driving the vehicle we can hear a distinct creaking/clunk over uneven roads or bumps. I know it's definitely coming from the rear since I had my wife drive while I sat in the back cargo area. I even went so far as to pop the back glass during one of the drives when back there and it was that much more apparent when I hung my head out the back. It seems more like a clunk when driving but a little more like a creak when backing out of the driveway. I believe it's a suspension related issue since it happens when there is some type of articulation of the suspension. It could be something loose but I got under the back end tonight and could not find a visible culprit. The only other thing I can think of is something with the e-brake since we do use it daily as our driveway is on a medium grade hill. I make sure when she parks it that she puts it in Neutral with her foot on the brake, put the e-brake on then let it take up the slack, then put it in park (that way not letting the transmission do the work). Those are my thoughts, any others?
Here are two possible TSBs but our build date was 05 - 2011 so I don't know if these apply...
Welcome to Jeep Hell! You can read back through page after page of this thread which has been going on for model years 2011 to 2014 to see a bunch of angry people. The problem is basically the rear shocks and shock mounts on quadra track II equipped JCS's which clunk and creak around 5 mph or any little bump. Jeep has changed shock absorber editions at least 4 times-maybe more. A couple of people said earlier that they finally got theirs quiet with the last edition of the shock but I think it continues for most, There werre 2 to 3 TSBs-the last one said to change the shocks--duh,
An earlier one had the dealer pulling shocks, greasing something and putting some kind of compound near the shock mount-insane--if it wasn't so infuriating it would be funny.
After 4 sets of shocks, I decided to check out the shocks and mounts. The top shock mount for the rear shocks is a piece of crap. It is a metal tab cantilevered out from the frame side of the wheel well. The end of it facing the wheel has no vertical support and I could stick my finger above the mount
You have to have access to the top part of the shock to change it but this mounting plate looks like it came off a chinese pedal car.
In desperation, I took lithium grease and packed it into the shock mount space until it was jam full. I then pulled down the joust cover and greased the plastic joust which is what the cover slots into. I then packed grease into every rear moving suspension joint I could. It has now been quiet for 5 months. Maybe I just got lucky, I don't know but so far so good but MT winter is coming so we will see. I'd go to the dealer and make them put on the latest shock as a first move. After that, your choices are live with it or go insane with gease like I did. I am a very neat person so slopping grease around made me ill but I was so po'd I would have made a human sacrifice out of a Chrysler engineer--that's an oxymoron for sure. Sadly this has continued up into some 2014 models. Anyway good luck! I wish you earlier success than I had!
