Metal damage Brain damage Undo a couple of rust encrusted bolts and big heavy metal things fall down go boom Freak'n lug nuts gave me the most trouble. Thank God for professional grade impact guns strong enough to snap off a few stubborn ones. Never did get 2 off the back driver side. Oh by the way... those really inexpensive Dickies work gloves .... great for repelling oil and other nasty stuff ... not so great repelling sparks ... 2 seconds with a cut off wheel and the damn things melted to the back of my hand. Not impressed.
