Anybody know how to cut-off the rear brake drum & hub on a PV544? Mine is rust-welded so badly that it simply won't come off no matter what technique I use. Spent over a month trying everything: (1) 5-hole hub puller, with and without torch heat; (2) 10 pound slide puller, with & without heat. Rust dissolve chemicals used: PB Blaster; Diesel fuel; Mixture of 50//50 Acetone & ATF transmission fluid. I'm DONE! Too much body damage swinging a 6 pound sledge hammer on the puller and a 10 pound slide hammer. And more of that and I'll damage the studs. So, how do you cut this thing off? Can it be done without trashing the axle half-shaft? I have the 4-1/2" angle grinder and I guess you need that. But where to cut, etc?
