I learned this trick from my buddy as well. Very sketchy! But it can give you added leverage if the wrenches don't flip out and fly off. I put my foot on the right most spot, and pushed as hard as I could! The wrenches were bending to the point of almost running out of space to push. I gave it just a little more juice and... CRACK! the stud moved a teeny tiny bit! After two more double wrench pushes I got if freed! Now to do the same on the passenger side. I'll save that for tomorrow.
