Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Sounds can be very hard to figure out via the internet and I'm afraid I don't have a quick go to answer I've run into before. Perhaps one of the other experts here will. But I do have a suggestion you might find helpful if nobody else steps in. You might try calling a few of the local chassis shops in your area and ask if the have a tech with a set of electronic chassis ears. Chassis guys are usually good at finding noises and I would guess that for 1 hour in diagnostic time or less you'll know what the culprit is. I hope this helps. Let me know if you'd like me to opt out and see if the others have anything to say.
