I was trying to install some rear differential inserts today. I ran into a problem with a 17mm nut. It wouldn't budge. I literally spent hours trying to get it to turn.
Tried a breaker bar, air impact gun, using a pipe for leverage. Was about to get the dremel and cut it off, but found a few more 17mm nuts that i need to get off that wont move, so that sort of stopped that idea.
Anyone have any tips?
