I have broken 2 arm pullers, gone through a bottle of PB blaster and cut through about 90% with a cut off tool and the stupid thing still will not come off. I do not want to cut any more for fear of hitting the splines and i have been banging on the cut with a chisel for an hour. I don't have access to a torch and obviously don't want to drive it after cutting through it so much. If anyone has any magic tricks on how to get this thing to come off please learn me your ways. Thanks!
Cut it again directly across from the other cut.
Easiest way I have found to take a pitman arm off is.
Put the puller on, place a long bar or pipe on top of the pitman arm, as close to the splines as you can get, one long enough that it sticks out on top of the engine.
Have someone tap on the bar as you tighten the puller.
If you do not have another person tighten the puller, tap on the bar a few times, tighten puller ect.
This has worked for me numerous times.
Even pulling old Waggy pitman arms off.
Remember to leave the nut on a few threads.
When the pitman arms do decide to come off they can come off like a bullet.

Thanks for the tip on leaving the nut on, that has been in the back of my mind the whole time. I will give all of these a go tomorrow and hopefully the fifth day is a charm. Looks like its back to the store for another puller.
BTW why are you changing the pittman arm they very seldon ever need to be replaced they are a NON wear part... only real reason to replace it may be if you put in a lift kit
I am in the middle of installing a 4in lift and will be putting another 1in body lift on next week. I seriously debated not switching out the pittman but after some research i decided with this much lift is was a good idea to switch. Now with the giant cut in it I am to far in to change my mind.
Pittman arms can be a real booger to pull, and when they finally give way, they come off with a BANG! You've done all the right things, PB blaster, heat, etc. At this point, complete the cut thru the arm. If you scuff up or cut some into the splines it will not weaken the steering shaft, nor in any way affect putting on the new arm so long as you dress up the edges of the cut to remove any burrs. I've cut off several that I could not get off with heat, PB, repeated efforts, etc. I don't cut away with total abandon, but cut down gradually til there is very little if anything left holding it together, then put in a thin chisel to spread the cut and they will fall off for you, or at least come off super easy with the puller then. Just complete your cut.
Don't shove on the new one dry, put a little anti-seize on the splines, or some wheel bearing grease. You never know when you may want to pull it off again.
....I'm not smart, but I can lift heavy things.......
Fill out your PROFILE, and don't forget to look in the FAQ for writeups
you want to heat the arm and not the splines and do it fast enough that the splined shaft doesnt expand with it. you have to be careful though because you can melt seals in the steering gear if you let to much heat transfer to it. i had to do mine a year ago and it took me 3 hours to get it off. very frustrating, and the rest of the project, 4 tie rod ends, to me 1 hour. good luck sir!
