I had an 03 w/ a 4.0L and LS rear end. I towed my YJ all over the place. To Moab, UT three times. Silver Lake at least 10 times. I had to have the rear end rebuilt 3 times. The last time it was on me. The last trip to Moab the trans gave me problems. I didn't think we would make it home. I had to pull the Jeep off the trailer going over the mountains near Vail Pass.
