The hub and drum are riveted together.There are 3 rivets centered between the 6 lugs. Some people grind them off and remove them so the drum can be removed without pulling the whole hub assembly off. Pull the dust cap off and remove the cotter key and remove the big nut. I use a crescent wrench. Pull the whole thing outwards. The bearing will slide out. Go slow. don't drop them on the floor. Just so you know.On the back brakes the drum slides off like normal.
