    I'm redoing my rear end and have to replace the pinion seal. The Chilton's says to measure the torque required to rotate the pinion and torque the new pinion nut so that I get that drag torque. The torque I get is 2 in/lb. It takes that to turn the pinion with not torque on the nut. How should I torque the nut? I chickened out of replacing the outer bearing because I didn't want to reshim the pinion. Should I replace the bearing while I have it all apart? There isn't any radial or axial play in the bearing that's there now.

    Did you take the nut off? If so, how much torque did it take to remove it? I think 250 ft lbs is proper for the nut. Should you change the outer bearing? Good question, you have to disassemble the rear end to get it out, since you'll need to drive the pinion out. I'd say do it, since a bearing could be bad or going bad and you'll not know till it's too late, and you're going through rebuilding the entire Jeep anyway. I take it that's your intention, basically leave no stone unturned?

    Glenn,
    I did take the nut of already, but I didn't measure the torque it took to break it (oops!). I want to do as much rebuild as I can, but I'm reluctant to disassemble the diff. (never built one before). I've already replaced the outer bearings and reshimed the axle. This 5 is going to be a daily driver with light trail use.
