Stuck Drum
Well, I searched for about an hour trying to find an answer but couldn't, so I guess I'll have to bother you guys
While my lh drum came off like it was greased (it kinda was with break fluid, whl cyl pretty much exploded) my rh drum is glued on. It seems to be stuck on the axle shaft. It move about 1/16", I engaged the parking brake and it doesn't move at all(as expected). I'm pretty sure I'm just moving the axle shaft. It's very rusty around the lug nuts and center cap thing.
My manual says to turn the adjusting wheel while pulling on the adjusting lever. Well I can't see a lever and it doesn't say anything about a lever in the diagram in the book. It also doesn't say which way to turn it. I tried turning it both ways and it moves about an 1/8 of a turn in each direction, no improved movement on the drum. I soaked the rusted area of the drum in wd-40 twice and gave it several wacks with a BFH. Is there anything else I can try?
Thanks guys, I know I'm getting to be a real pain in the ***

Re: Stuck Drum
Get two hammers, place one against the drum between the lug bolts, use the other hammer to hit it really hard. This will break loose the drum. WD-40 will help!

Re: Stuck Drum
Look at the backing plate and see if there's rubber plug there to cover a hole. Or if there's a hole so that you can loosen the adjuster with a flat screwdriver.It should be perpendicular and below the axle..Loosen that as much as you can. If its still stuch then take the retaining springs off in the back and see if it will give you enough movement to pry it apart

Re: Stuck Drum
Thanks for the replies guys. I tried adjusting the parking brake several times. Tried turning the adjusting wheel both ways but couldn't get it to turn very far and got no improvement. Thanks for the clarification though, I wasn't really sure how to do it with the manual's crappy description.
Thanks for the hammer idea, but I got one question for ya. I assume that you mean put the hammer in between two of the lug bolts and not on the center. Just don't wanna hit something wrong and screw up my axle shaft.
Thanks a lot guys

Re: Stuck Drum
I usually replace the drums when I do the brakes on my cars anyway - I have a 3lbs mini-sledge and wail on the lip on the back of the drum, making sure I don't hit the backing plate.
When I did my Jeep the cylinder had a leak and all the mud that got side the drum became a big greasy concrete block. That was the only way it came off and it took much persuation, most of the time a couple of good whacks from the back gets it moving enough to get it off like usual with some wiggling.
