Annoying Clunk!
I have a similar clunk noise when going over bumps that seems to be coming from the driver side doors or b-pillar. I'm thinking it's the rear door because the rear door paint has a few dings around the latch like it has hit the adjacent metal plate that the striker is attached to. I will raise this with my dealer tomorrow.
I too experienced the annoying clunk noise from the driver door. After reading some of the comments on this thread I first torqued the striker latch on the piller to 25 ft-lbs. This reduced the clunk noise considerably, but did not eliminate it. I know I was on the right track so I lowered the striker latch about 1/16" and that eliminated the noise completely, but the door was difficult to close. I noticed the outer door panel was not lined up with the rest of the body. I must have accidentally moved the striker latch inward as well as downward, causing the door to close too far inward. I readjusted the latch outward slightly until the door was even with the pillar. The clunk was gone completely and the door closed smoother than when I bought the JK. Before making these adjustments I had to slam the door,often twice, for it to close properly. Now it closes normally like all the other doors and no more annoying clunk noise. (Note: Mark the original vertical and horizontal latch location with blue tape and make very small adjustments - no more than 1/32" to 1/16" at a time.)
Nice work fellas... been having that damn clunk ever since I put my hard top and doors back on. Had it on both B-pillars. I moved each striker up slightly to center it for the latch assembly and it seemed to work so far. Plus I torqued them down to 26lbs... which was actually tighter than I thought... I went around at first and tightened them pretty good but 26lbs was a bit more!
