One word of caution before you all go pulling you axle shafts out, the bolts on the end of the hub hold the axle in, but when you pull it out, gear oil can come out, so dont make a mess! Once you get the axles out the rest of the dissassembly is just like the front. You can buy a kit if you want but the rotors and calipers are from a 73-87 C20. That and the caliper brackets are all you need besides flex lines. Really simple. oh you might want new studs also since you'll be pressing them out and back in. As far as the newer versions that have a drum you can remove w/o disassembling the hub, I've never seen one, so I dont know.
