On my 99 e300. Apparently the person before me cranked one particular one down as tight as the impact would go. The head is already angling up as I was trying to break it lose with a breaker bar. If the head twists off, will I still be able to get the wheel off (the other 4 lugs are fine) or is there something in the design of this lug stud that's going to cause it to stick? I have a magnetic induction heater if I can just get the wheel off. I'm guessing this is probably best left to a shop that can just weld a nut in place on the end and try to get it out that way?
