yeah i snapped one. Had a 3 foot breaker bar on it and slowly pushing and CLICK.
but it didn't matter cause i was in school, and we took an air chisel to the welded stud on the other side, busted it off, welded a washer in it's place, and replaced it with a nut and bolt
otherwise the rears went very smoothly, and i had them done in a little over 2 hours.
