Ive had my 2007 Unlimited X into the shop twice and the dealer cant replicate the wierd noise Im getting. The noise is kind of a clicking or creaking kind of noise. Its nery faint and because of that I only notice it atleast at low speeds. Its an automatic, and anytime I shift from drive to reverse, it will stop, or if I hear it in reverse and go to drive, it stops. It doesnt seem like something major but I want to get it figured out. Any ideas what this could be?
