Okay, so i have a 2001 xj with 96000 miles. I have had this stupid issue where when i let of the gas there is a bad noise coming from the rear. We replaced the axle and that didnt help so my friend and i were looking under the car and i started to shake it. there was a clunk noise coming from the t case right where the drive shaft goes in the slip yoke. I dont know what this could be but iam almost certain this is my issue. On this diagram could someone point out what i would have to replace?
