Does anyone have a sure-fire way of getting the rear drums off of these dual-wheeled beasts? I pulled the wheels off the passenger side last night...Everything came off nicely except for one lug nut. I broke a 3/4 breaker bar doing that. I had soaked the lug nuts in Deep Creep and PB Blaster too. The drum isn't budging at all! I had to drill out two of the flat head screws that hold the drum to the axle as well. I am thinking heat...Can anyone give me some advice before I break something? Thanks, Jim.
