Have to go look at a 97 TJ thats for sale. Owner says hes had it for 3-4 years, and its always had a clicking only when in reverse. I dont know if its linked to rpm, or if it has gotten louder or not. I thought I would go talk to him in person. he says hes never had it looked at, and his guess is the chain in the transfer case. I find it hrd that hes never had it looked at considering the jeeps only got 137,000KM on it. Cant keep from wondering if hes hiding something. and wondering if anybody has had this problem? Thanx.
