Remove the single small bolt from the bottom side of the caliper. Drive the pin out with a mallet and punch. Don't let the calipers hang from the hoses. Take the allen screws out of the 4X4 hub, and remove the hub. Take the lock nut off the end of the spindle. There will be another nut behind that one (I hope, my memory is fuzzy). Somewhere in there, there may also be a washer with a pin sticking out of it. All these things come out in an obvious fashion. Just pay attention so you can put it all back together correctly. The outer bearing will come off if you push on the disc one way or another. Once the outer bearing is off, then just slide the hub assembly off. Put the hub on a bench, and use a drift to knock the inner bearing out, pushing the rear seal off with it. Now examine the races. They are pressed in, and have to be knocked out. Use a drift to catch the small lip on the inside of each race and knock it out. Move your punch around in a circle to knock it out streight so as not to **** it. Clean everything really well. Hammer the new races in evenly, and carefully. Make sure they seat fully. Pack your larger inner bearing with clean grease really well, and lay it on the race. Now put the new inner seal on, being carefully to tap lightly all the way around to seat it. Be sure not to distort it. Clean up the spindle real well, and lube it lightly with grease. Slide the hub on, being carefull not to nick the seal. Place your well packed small outer bearing on, and reassemble. You'll need to torque the first nut to spec, which I can't recall what that is right now. Hopefully somebody can post it for you.
