If you are POSITIVE that the tool is clickin in there, then its just a matter of beating the $hit out of them to break em free
They are just spring loaded little bastards, but they do put a hurtin on ya and piss you off pretty quick...
Just try squirtin some penatrating fluid in there as well as twisting them instead of just yankin...
May the force be with you
