I've got a 98 TJ running a D44 front/rear with lockers and 35s. I drove 80 miles to Uwharrie Natl Forest and wheeled all weekend, then made the trip home. No problems at all. The next morning when I went to back out of my driveway, the rear didn't "feel" right. I stopped in the street in front of my house and hopped out to take a look......the passenger rear axle had toasted the bearing and had slid out about 10"!!!!!! No idea how I made the 80 mile trip home the night before, but glad she waited until I was home before letting go.
