help with stuck nut

[shadowpr]

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?

if its really cold where you are at, that may have an effect. try getting some heat down there to see if you can loosen up the frozen locktight.

Yeah, i think it got up to 33 today. I'm a bit worried to use a torch to heat things up under there.

Yes, but the consensus is PB Blaster is better.

Spray liberally and let it soak. Repeat. Another optional repeat.

Good luck.

you can pick pb blaster up at any automotive place, i think even walmart and lowes.
