What you want to accomplish isnt too difficult of a job. Heres the steps
1) Jack up truck, take tires off all that crap etc...
2) Take off your calipers and put your new pads in and hang up the caliper with some wire so it doesnt just free hang
3) Take out the locking hubs
a) Take off the dial/cover and lay it aside
b) There will be a snap ring holding the hub body inside the wheel hub,
there might be one large one riding on the outside of the wheel hub
and a small regular one on the axle shaft end. Dont remember though.
4) Time to pull the hub body out of the wheel hub, I take 2 of the screws
that hold the dial on and screw them into the hub body to use them as
"handles" to pull the body out.
5) Grab your hub socket (big 4 prong socket) and turn off the first lock nut,
behind that should be a washer, then turn off the second lock nut and pull
it out.
6) Rotor/Hub should pull off now
7) Need to separate the hub from the rotor, pound out the wheel studs to
separate
8) Remove the wheel bearings, and wheel seal then you can remove the
bearing races using a brass drift or whatever youve got (If you have a
grinder, save a set of the races so you can grind material off of them
and use them to pound the new ones in)
9) Put your new races in the hub either using a brass drift or the method
mentioned above (carefull not to nick or scar the race)
10) Attach the new rotor to hub
11) Pack wheel bearings and throw the back one in and put the new wheel
seal in, I wait to put the outer bearing in until i get the hub onto the
spindle.
12) Now that you've completed the brake part of the job you can do the axle
joints
13) Take off the bolts holding the spindle on, it might be frozen on there so
you can take a block of wood and beat the spindle so it comes free of
the knuckle
14) Slide spindle off and then you can pull axle out of the differential
15) You should have no trouble replacing the u-joints, maybe have somebody
help hold the axle so its easier to work with
16) Put axle back into diff and throw spindle back on
17) Slide your hub onto the spindle and put that outer bearing into the hub
and slide the whole thing all the way up onto the spindle
18) Put your first lock nut onto the spindle and tighten it down, I tighten it
until I get a slight drag when I turn the hub (its all a feel thing for me)
19) Put washer in and then tighten up the outer lock nut
20) Throw the locking hub back together and put your calipers on and you're
done.
It isnt a bad job at all
