[QUOTE="JerryD, post: 450858, member: 17662"] Here's a write up from another forum by a member that hasn't logged in in 9 years... ------------------ [B]Tailgate Clunk Fix - Tailgate Adjustment - [/B][I]by Incognito [/I][B][/B] It's kind of funny, but around this time of year you hear about quite a few people experiencing "tailgate clunk". Last year (around this time) mine started making it as well, about the same time my TPMS went off. It probably has a lot to do with declining temperatures. In any event, after being thoroughly annoyed for a couple of weeks, I decided to fix it. So long as you haven't placed excessive weight on the tailgate (i.e. oversized tires, jerry cans, ect.), the majority of these issues can be addressed by making minute adjustments to the latching assembly. The parts in particular to adjust will be the striker, stabilizer, and stabilizer cup. Basically the way it works is, the striker is what the tailgate latches on to when it is closed. For the most part, you probably won’t need to adjust this one. Then there’s the stabilizer. This is actually what will support the majority of the tailgate on the driver’s side. This in turn goes into and mates with the stabilizer cup. The way I adjusted mine over a year ago, and is still clunk free to this day, was to loosen and move the stabilizer up and towards the rear approximately 1-2 millimeters, just a tiny bit. This should take care of it but obviously yours may require more tweaking. The important thing here is to have your tailgate lined up perfectly with the body of the Jeep when you are done, and to not have to slam the door excessively hard afterwards. By making very small adjustments to these three components, this can be achieved. I'd suggest starting by simply adjusting the stabilizer and see if that works first before messing with the other two.
