ok I have a 1994 Jeep Grand Cherokee Laredo ALL Wheel Drive. I'm getting a clicking in the rear end when it's not under load and I've replaced both rear U-Joints, inner and outer bearings and outer seals and I'm still getting the same clicking and grinding noise, Not louder not quieter! I've removed the rear drive shaft and didn't hear it anymore so that narrowed it down to the rear end, but all the gears looks fine with NO chips or teeth missing. Someone please help me out with this!
sounds like cracked ring !
might be a bearing starting to go
