Pitman arm nut seized!

[Hootbro]

I've tried almost everything from 30" long 3/4" drive breaker bar, and my sons 1,000# Ingersoll Impact gun. Even used a cheater pipe on the breaker bar and snapped the crap out of sons extensions. I have a intrusion heater to heat the bolt and hopefully that will do it.
If anything else I'll go to HF and get one of their 1,700# impact gun and use it on the heated nut!
We'll see.

At that point, I would be getting a cutting wheel and splitting that nut. May nick the threads on the steering gear shaft but they are coarse enough it should not matter

Because each one of those impacts from the hammer is being transmitted right into the gears of the steering box which isn't made to handle that kind of force.

It handles the enormous force and stress of steering a jeep. Even with stock tires sizes, that’s SO much force.

I’d try the induction heater to kill that loctite first, but then I might be with you. You wouldn’t even need to go all the way through to get close to the threads. Just take a few notches out carefully, which will weaken it. Then put a socket on it and hope it fractures and breaks away.

Yeah, he just has to get that friction lock broken. I just hate to see him put the coin out for ever larger tools. When non-destructive does not work, time for destructive methods.

Almost makes me wonder if the nut was spin on and stripped the threads fusing them?

That is exactly my last recourse!

Force and impulse are not the same. Force is just a force, but impulse if force over time. The point of an impact is to multiply a rather small force by making it happen in a very short period of time.

Take a hammer and a nail. You can put a lot of force on a nail and it won't go into a board, but use a rather light hammer that imparts that force very quickly and it will go right in.

You broke a 3/4" extension? Wow.

Yup, here are pictures of the victim!

That thought has honestly crossed my mind.

Nut body side profile is not that big. A Dremel with a cutting wheel attachment should do it. Soon as you see threads showing on the cut, stop and whack the cut line with a cold chisel and a BFH and it should split

You are loosing a lot of energy using such a long extension. Something that long will twist like a spring. Just use the breaker bar and socket directly and put a pipe on the breaker bar to get more leverage.

Mine was loose from the factory. 18 inch 1/2 inch wrench and a 42mm socket took it off with out even having to resort to cussing.

I love a good reason to buy a tool.

Agreed. I use my floor jack handle on a really stout, but short 1/2” ratchet. And I use the one I don’t love.

I had a shop in 2022 install mine without loctite. It loosened within months. I’m glad I’m not dead.

Late to the party, but slicing nearly all the way through and then tapping the gap with a chisel would've been the least risky and least costly move here. A new nut is way less $$$ than all the tools that have been bought and destroyed here.
