hey guys, trying to install my lower hd control arms today but couldnt get the bolt undone on the chasis end of the lower control arms. has anyone had this problem before and if so how did you manage to undo the sucker? i had over 1m of extension bars on it and couldnt get it undone, rattle gun couldnt do it and then resorted to using a breaker bar on it and using a car jack to move the handle up using the trolls weight to push against and still no luck...........!!!!!!!!!!!!!!!!!!!!!!!!
