you will hear a lot of weird noises from these jk's. my friend has one and his has completely different noises then mine but just as many. try adjusting the plastic molding that covers your stereo and vents. or put a six inch piece of foam below the top plastic clamps. that was a quick fix for me. also if you added a larger spare tire on the stock tire mount, you will hear an extremely obnoxious rattle in cold weather. seems to be a problem with a few of these
