I have the same problem... one drum came off pretty easy, on the other it almost seems as if the shoe has worn into the drum, because the drum is really loose when fully on, to about halfway off, then it just becomes a huge PITA. I have hit the snot outta it, and grease it up big time, and pried and pried.. still no luck. Makes me wonder what special tool a shop would have for a job like this.
