I have a 1998 Mustang that needs new U joints, but I still can’t get the damn bolts to break loose. So far I’ve tried: Jacking up on a wrench that’s on the bolt, it picked the back end of the car up. I tried PB blaster, blowtorch, wd40, kicking, hammering, and so far I got 1 bolt to come loose at the expense of my knuckles and a wrench. (It snapped in half) and my other wrench just keeps bending. I’m completely lost.
