Gotta watch using torches on those things. Stay clear everything. Cut the edge off and get the stud out quickly. I was cutting the rivets out of a control arm to remove the ball joint while I had the frame out replacing the transmission assembly. The heat transferred into the joint and it couldn’t expel the pressure fast enough resulting in a broken fusion weld and a boom so loud my ears still ring. The hot grease cup was propelled through my PPE and it imbedded itself in my eye socket. I now only have one eye, a crushed nasal cavity, and nerve damage. Be careful everyone.
