I know I did a step by step on these, and as I recall someone else recenly posted something with more detail also.
Anyway, if you have the integrated hub/drum like I do, and sounds like what 3B is describing, it's not real hard to take apart.

First take off the hub cover and pull out the axle.
Next, you should be able to see the top nut and locking tabs around the outer edge. Bend back the tabs and use a drift punch to remove the outer nut.
Next you'll remove the locking plate, the inner nut, and the washer as seen here. After that it's just a matter of sliding the drum off.

I have my wheels on in those photos because I didn't have access to powrfull enough tools so I pulled them off all at once to take in to be torn down.

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
