Stuck nuts

[Jonathan_S]

Either break the bolt or loosen the nut, it will eventually happen

[JWEBB]

Grind it off?

[RockChuck]

You talking about the pinion nut? Large impact should do it, if rusty I’d use penetrating oil and let it sit overnight

[Humptulips]

Old school is heat and apply bees wax. The heat draws the wax into the threads. I have had that work when penetrating oil failed to loosen things up.

What a thread title!

Squirt the cricket piss to it and let it sit overnight. Or mild heat from a torch.

The thread title brought me here.    my input... good luck. I have stuff on my truck I couldnt undo so it still needs fixing, but cant get the bolts undone. Its been like that since 2011 its fine I am sure, exhaust systems are over rated.

Atf and acetone,   torch, and use a large pipe wrench to hold the flange while air impacting the nut off.

That's interesting. I'm going to keep that one in my back pocket to try next time.

You should not heat that pinion nut or cut or anything else these people are suggesting. It should come off with an impact. The nut and pinion stem should be marked to get same pinion bearing preload when reinstalling. Too loose or tight can cost you a rebuild and that aint cheap.

If it is indeed the pinion nut you are talking about,  Get a good impact gun and an air compressor with enough cfm for the impact to work properly and it will come off.

Obviously he has not reached the required minimum of bloody knuckles yet or it would have come loose by now.

I usually just keep adding length to my breaker bar, it is amazing how many items you can daisychain to extend your breaker bar, LOL

Soak the area in Kroil and come back the next day with a tool long enough to get good leverage. It will come off.

   put a chunk of wood/pipe under pipe wrench as need to hold pinion.   Cheater pipe on wrench helps - need 3/4 inch drive on the trucks. 

[PolarBear]

Torch it, heat it up a bit

Love a good daisy chain
