OSHA "Unapproved"

A couple years back, I was changing brake rotors. One of the back ones would not come off. I've got a pretty big gear puller. I put it on and cranked it tight. I came out of the garage every 10 minutes and gave it a couple swats with a sledge. About 2 hours later I heard a Big Bang, I thought the truck fell off the Jack.
I anti seize everything now. That's the price you pay for PennDOT using salt and brine to treat roads.
