After a relatively mild trip in/around Moab the Jeep started making a noise like the mild roar of tire tread. Didn’t think too much about it but it started getting worse and several hundred miles later it was obvious the noise was not tires. Jacked up the rear end and slapped jack stands under the axels. Noise was coming from the rear diff and was almost certainly in the pinion area. Took it to a mechanic I trust because I didn’t have time to work on it. He agreed it sounded and felt (because of the heat) that it was probably the pinion bearings. Took it home around 25 miles and the noise was getting louder. Parked it and ordered new pinion bearings, races, nut, seal etc. Got all of it together and headed back to the mechanic. By now the noise is LOUD. Didn’t think I would make it. Mechanic just called me and said we were right front pinion bearing was shot and several shims were eaten up. He replaced both bearings and set it all back to specs (they were all correct and tooth pattern correct before he took it apart) However on the test drive the noise is louder than before. He jacked it back up but can’t pin point the source, other than to say it is coming from the rear axle area. TC and Tranny are quite. The wheel bearings were good and the locker engages. Axle shafts are straight. The only thing left is the locker itself. Anyone had this kind of experience with the tru-lok? Noise is most pronounced at neutral meaning not at coast but not under load.
