How do you get the rear drum off a 2004 Pontiac Montana?

LOL.. This has got to be the dumbest question I have ever seen. But I will answer it anway way. All you need to do is romove the tire.... I am sure you are aware of how to do that. Then just pull the drum off. If it seems to be stuck jus get a hamer and bang it off. [The above answer is correct, although I challenge it as being a dumb question. Just finished my 2003 Montana. After you remove the tire, if the rear brakes have not been changed before, there are two "star" clips that are used to hold the drum in place during its ride down the assembly line. These need to be removed and you don't really need to put them back on. I used a screwdriver to pry up the tangs until it was loose and I could remove them. If your brakes are badly worn, you may need to back off the shoes. There is an oval rubber insert in the back of brake plate (need to put you head in the wheel well to see it. Pry it out with a screwdriver. There is a star wheel inside that you turn with either a screwdriver or special tool to back off the brakes a bit so they don't catch on the drum when you go to pull it off. Ideally, LOL above says "pull the drum off." Mine didn't come off - easier said than done! It looked like the hub and drum were one-piece and weren't moving. I pryed on the back of the brakes - DON'T DO THIS. There is a sheet metal dust shield that I bent. I went to the Internet and found this link. I was worried about breaking something by hitting the drum, knocking it out-of-round, so I started slow. This is what worked for me. Get some penetrating or other thin oil and spray it around where the hub and the drum meet. Give it some time to penetrate. (Nothing happened.) Hit it with a small hammer - nothing. Hit it with a bigger hammer - still nothing. Go get the sledge - still nothing. Grab the propane torch and start heating it evenly around the drum, between the lugs and the hub. Add some more penetrating oil. Start knocking it back and forth, up and down, round and round with the sledge. Notice when it starts to move. Once it is broken free, then you can grab it and just pull it off (wear gloves if it is hot from the torch. It is easy after it is all done! Good luck.]
