    Should be a full floating axle. You should see 6-8 smaller bolts on the center hub. Remove those, and that is the axle shaft=pull it out=should come out easy. Then you should see a retainer nut that holds the wheel bearings in place=remove nut. Now the hub/drum assembly should be loose=pull it off (may want to stick if there is a rust ridge built up on the inside of the drum). Now, remove the brake line (be careful not to twist the line) to the wheel cylinder and then remove the wheel cylinder by working past the brake shoes if you choose not to remove those (may have a spacial clip if their are no bolts holding them on the outside of the backing plate). Install the new wheel cylinder, reinstall the hub/drum, install and tighten the nut, build a grease dam from the bottom of the hub about half way up and try to fill the hub (where the wheel bearings are) up with the proper weight gear oil. Reinstall the axle shaft and bolts, tighten. Bleed brakes, install wheels, check rear axle fluid level, and test drive (being sure to do large figure 8s in a parking lot to properly get the fluid to the wheel bearings). It shouldn't be too bad of a job even though there are a lot of steps. GOOD LUCK, Dave
