You have to pull the axle by removing the axle nuts.Next you will see large nuts on the axle housing. There is a lock ring tab that holds the outer nut from turning,you have to bend the tabs back so you can loosen the nut. I have a socket for the nuts, but you can use a punch "carefully" to loosen them. Turn the outer nut off, pull the lock ring out, loosen the inner nut, turn it off , pull on the drum a little to get it off. A little trickey at times if you get the bearings cocked. Then remove the drum and hub assembly. Mine was stuck so bad I had to use a couple of pry bars between the drum and backing plate to get it to move. This must be done carefully , so you don't bend the backing plate. I think I covered everything Hope this helps, If not let me know. I know the inner bearing stays in the hub, can't remember about the outer.
