if u got the dough go to a rental store and get u a small compressor and an air chisel. i had to use one on my old jeep. 3 different sledge hammers homemade expander. [a clamp cut in half flip them backwards and put the halfs of c clamp back on the big screw n when u turn the arm of the clamp it pushes out instead of in] didnt work. air chisel just chisel turn it some chisel turn it some more chisel etc etc. that got mine off. ---------- Post added at 11:04 AM ---------- Previous post was at 11:01 AM ---------- or rent a ductile iron cutoff saw made buy stihl. just cut the drum off. when all else fails its sometimes what u gotta ive had to use a cutoff wheel to get stuck bolts off the brake caliper once. hey u could also try pb let it soak n dry then get a propane torch and het it then hit with a sledge. or try the opposite and get a can of that freeze off. might be cheaper.
