Also mark the caps before you take them off. Use 2 prybars to get the carrier out, pry on the ring gear bolts. Check to make sure the axles aren't pitted, if they are try sanding them up, if that doesnt work then you need a new axle (or redi sleeve which i havent seen) otherwise it'll tear up the new seal. Put grease on the spring and around the seal where the axle rides. The easiest way is to get an aluminum puck a little bigger then the diameter of the seal and a long bar, and have someone hold the puck and seal while another taps it in. When you put the shims back in put the left side in with the carrier and tap the right side shim in with the cap, otherwise you'll break it, unless there is no preload.
