Dude, I'm fairly certain I'm the first to even attempt removing these mothers - and they ain't giving it up! Copious amounts of WD-40 and a 250lb impact wrench did nothing. Ratchet and hammer did nothing. I didn't have much room to pull, but "The Negotiator" (5ft steel pipe) did nothing but break my ratchet. Tomorrow I'll try heat, wax or something else.
