    The problem we get on a lot of Jeep Grand Cherokee's is that a lot of people change the transmission, and they increase the output of torque to make them more of a working machine.  This makes it tough to know quite what to do with bearings and nuts.  If your car has been modified at all, please make sure you know the exact modifications before installing anything to avoid future strain.

    The pinion nut torque is minimum of 160 ft. lbs. Then you need to check the amount of torque it takes to rotate the pinion. You are looking for a rotating torque of 10 to 20 in. lbs. for used bearings and 15 to 35 in. lbs for new.  Increase the pinion nut torque by 5 ft. lbs. and recheck until rotating torque spec. is reached. If you go over 260 ft. lbs. you have a spacer problem.

    The pinion nut is 160-180 torque depending on if your upgrading the front differential to different gears. If your not I would go back to what the factory shims are set

    Use thread locker on the pinion nut threads. Have had too many of the Chrysler pinion nuts back off. Even have seen factory installed pinion nuts back off.

    I'm sure you could have found the specs on Google.
