in the haynes it even says 75 lbs...you figure they are the 3 bolts holding the front wheels in place....all the axle-nut does is hold together the bearing w/ the outer shaft.
I'm running 31/10.5's on 15x8 Cragars with 3.75" backspacing. I had started to think that because I have such little backspacing that the extra stress from that was killing them. But, I bought the jeep with 70,000 miles on it and ran it until 78,000 when the first hub went out. Oh, and those were the factory original hubs at the time. Now Ive only put 4500 miles on it and they are shot again.

Well I'm going to tear down on Sunday and give it a good look over. Gonna check the u-joints and tre's. I'll then take it to have it aligned. Gonna get by tires balanced as well to see if that helps.

Tires are in good shape. about 60% left on them. The do have some chunking from rocks and whatnot but it's nothing big. I'm going to have them balanced just for extra measure.
