    Going to be regearing my 30 tommorow to a 4:10 i have a bare XJ housing and a set of gears and a carrier from a YJ as well as a master install kit.. Only question I have is setting pinion depth with the shims whats the best way to do it?

    do you have a dial indicator?

    more importantly:

      I can most likely get my hands on one... However im really talking about the shims that take the place of a crush collar on this one..

        Ask Google what is a good starting shim size or reuse your old one.

        Remember the carrier bearing caps are matched so mark left right up down.

        Install the pinion don't worry about pinion preload until the depth is set. Just install it and torque down the pinion until it is about as hard as you can turn a screwdriver.

        Then install your carrier set the backlash.
        Then put marking compound on it and read the pattern adjust the shims accordingly.

        Repeat until your pattern is good this can take a few tries that is why setup bearings are nice you don't have to press them on and off every a million times.

        I have the pinion depth tool so I just set it to the depth written on the pinion and double check with the pattern.

        Once you got the pinion depth set then you set the pinion preload, if this is a crush collar make sure you have the bearing and seal in place first.

        Then you add about .010 shims to both sides of the carrier for the carrier bearing preload and double check the backlash. You should really have to force the carrier in with the hammer it shouldn't just fall in especially if you're not using a case spreader.

        Tools you will need
        giant clown hammer (big dead blow)
        calipers to measure shims,
        dial indicator to measure backlash,
        in_lb torque wrench for pinion preload you can usually get by with feel after a while.
        A case spreader is good idea to get the correct amount of carrier preload.
        If your replacing the inner seals the seal installer makes your job a million times easier.
        Pinion depth tool or extra tries.
        Setup bearings makes the job faster and less chance of F-ing up the bearings. Bearing race installer or something to hit them in.
        Torque wrench for the ring gear bolts an the bearing caps.
        Loctite for all the bolts
        And a large prybar to get the carrier out once you hit it in it is hard to get out.
        Silicone don't forger to put it under the pinion to seal off the pinion splines to yoke.


        Good luck.
