Okay...so today I checked the gear oil level in the diff. It was good. I then added a second tube of LSD additive. I lubed the 3 zerk fittings on the driveshaft with Mobil1 synth grease. I removed the rear right tire and inspected the brakes and rotor. Everything is or appears good.
Went for a test drive. I am getting a clunking sound (almost like something binding) while driving straight. The sound sounds like it is coming from the right rear although it could just be transmiting to that area. The noise dos not happen all the time It will happen 2 or 3 times real quick then not happen again for a while. I am stumped. Anyone have any more Ideas? I've got 2 weeks to figure this out before I head to Moab.
