14 wrangler sport that has a super annoying rattle/clunk (best way I can describe the noise). This only happens when I'm idling, and it doesn't happen all the time, but it is often enough for it to be a bother and it's noticeable enough for people to stare when I'm at a red light or what not...once i put it in park it stops. The hotter the day, the quicker the rattle begins. Yes I know its a jeep and it's bound to come with creaks and rattles, but this one is nagging at me. I've taken it to dealer and they couldn't find what was wrong with it. I was in a fender bender a couple years back...barely even scratched up my front bumper (gotta love that XRC). Any ideas?
