Is there something I am missing or is this thing impossible to break loose, I doused it with rust loosener and I cannot get this thing out, I cant remeber what we did on my other car but I cannot get it loose. any tips?
 
I've taken off numerous stubburn bolts, nuts, ect. The one thing they all seem to hate is, HEAT. Get up there with a small torch and heat the area up. It should break loose. Some leverage with a long ratchet won't hurt either...
