Ouch! I put my pick up (99 Chevy 1/2 ton Ext. cab) up on stands to replace a broken wheel stud. I was sitting in a little snap on roll around chair swinging a 2 pounder, beating out the stud. Little did I know, I was actually beating the hole truck off of the stands. It fell and the passenger side rocker, just under the pass. door landed on my left knee. I was fortunate enough to pull myself out from under several seconds later when my ankle blew out!
I now have two $10,000 titanium 3" drywall screws holding my ankle together. I will see if I can dig up the x-rays and pics.
I now have a small fear of being under anything supported by jack stands!:confused:
