[Classic Heartbeat]

Sounds like to me that you have brake or brake hardware issues. If there are not any clips on the studs holding the drums on, and you have sprayed the studs and around the end of the axle with penitrating oil and your drums still don's slip off, your shores or whats left of them has eaten wrtight into the drums. The only way to remove the drum is by backing the slack adjusters with a screw driver or brake tool. Then remove the drums and replace the brakes, wheel cylenders and I also would by a brake kit witch will have all new hardware. You can buy new slack adjusters if yours are bad also, or sometimes you can spray them with penitrating oil to loosen them up. and work them free. WES
