to take off the rear drum there is a 1"1/8 inch bolt on the rear end. undo and straight towards you. if u pull side to side you may ruin your wheel bearing. ive done this along and its extremely easy to do and will cost around 95 bucks to replace the bearing and then u gotta get the old one pushed out so just pull straight off.
its a 30 mm bolt just to save sopme one the trouble of two trips to the parts/tools store.
