The problem really isnt that they are stuck that bad, its just sooooo hard to get to everything because of how tight it is. The cheap impact wrench I got will not break anything, trust me I can about hold the socket back with my hand, but it might be just what I need. It only cost $19.99 and is 12v, the little jolt it gives might be just enough to break the nuts. I did use wd-40, I probably should have used something a bit better though.
