    85 CJ7. Pulling out axels

    AMC 20 rear end. One piece Yukon Chrome moly axels. Has an aftermarket air locker diff. Pinion bearing pooped the bed and I am rebuilding. I do not know the brand of the air locker. I need to pull the axels to rebuild. I am a rookie. Sorry.

    The axle shafts on that axle are retained by the 4 bolt flanges at the outer ends. These are the same bolts that retain the brake backing plates.

    If you are new to this, do you have access to a press and bearing separator to replace the inner pinion bearing? Don't forget to keep track of all of the shims when you disassemble the pinion and remove the races. It also wouldn't hurt to double check the pinion depth when the new bearings have been installed to make sure you are good to go. There is no guaranty that the new bearings and races will be exactly the same thickness.

    That was quick thank you. You mean the nuts on the outside? The same side as the brake shoes ECT? then just brute force and they come free?

    That is correct. Assuming the shafts are using tapered roller bearings and not ball bearings, there shouldn't be much of any brute force required once the nuts and backing plate are removed, though. There isn't anything pressed in if tapered roller bearings are used. The bearing retainer is held in with the 4 bolts and the bearing and shaft will come out easily with the retainer. The race is pressed into the housing but it does not need to be touched unless it is to be replaced.

    Those are it. I don't think you need to pull the brake lines, but I'll defer to CTD.

    I think it will depend on the backing plate....but you should be able to leave the backing plate in place and therefore not have to touch anything on the brakes. Just remove the nuts and the bearing retainer plate will come out with the shaft.
