1. Lift rear or entire vehicle SAFELY!

3. Remove the rear wheels.
4. Remove the rear brake calipers.
5. Remove the brake drum/disk.
6. Remove the cotter pin and use an air driven impact wrench to remove the stub axel nut (castle type). This nut is torqued to about 350 ft/lbs and requires a 36mm socket.
7. Remove the hub.  You may have to give this a whack with a mallet.
8. Use a (8mm?)12 point "Cheese head" Allen wrench to remove the CV joint bolts.

12. Pull the stub axel out of the trailing arm.  You may need to use a gear puller, or drift it out using a hammer and a section of 2"x4" lumber.  A soft faced mallet will also work.
13. Use a screw driver to carefully pry out the inner and outer bearing seals.
14. Use snap ring pliers to remove the inner bearing snap ring.
15. Use a drift punch, or a small piece of wood (Maple is excellent) to drive out the bearings.
16. Remove ALL of the grease from the bearing box  and repack with fresh grease.
17. Pack and install the bearings (Don't forget the inner bearing snap ring!).  You will have to use a hammer and drift to seat the bearings.
