Ok I know I've been asking alot of quetions lately but hey that's how you learn right? Well that and research. Anyway I saw the post before about someone else having trouble getting their pitman arm off. I heated it up on the sides like Ivan suggested and I've got a puller on there but this thing will not come off. I'm at my last resort here. I was going to cut a chunk out of it. Hopefully a chunk large enough to let it come off. I'm just worried about cutting into the steering shaft.
So I thought I'd ask what you guys would do.
(By the way this thing has been soaking in PB blaster for the whole week)
Please help my new pitman from Shaker Built showed up I'd like to get it on today.
I cut a grove in mine with a angle grinder with a cuttoff wheel. Didn't cut all the way through but left a 1/8 inch there then smacked it with a chissel and it came off easy after that.
yea, a little propane torch is just a waste of time. i ended up using a balljoint fork on mine, because when i was in high school thats all i had. now i would use either a torch or cut it off with a cutoff wheel

DO THIS!!!!!!! ^^^^^^
I have to do it at work quite often with IFS Chevys.
i have used 2 tools that ALWAYS works, a pitman arm puller and a BFH! get a good bit of tension on the pitman arm with the puller then with the BFH smack the hell out of it a couple times then tighten the puller down some more. it will move! i dont like using heat b/c you can potentially screw up the lower seal and then you have a nice leaky gearbox. as for the grinding.... geez, that'll take all day!
i couldnt get my pitman arm to come apart from my drag link awhile back. put a pitman arm puller on the thing and loaded it up with tension. hit it with an air hammer pretty good. it popped after about 45 seconds. same idea should work in your scenario. working on my old rust bucket i've found more than a few parts that the air hammer has taken care of from being frozen in place.
I usually use the method that fishy stated...also it is much easier to take the steering box off of the vehicle instead of struggleing around with it in the engine bay.
There's a laaaaaarge range of heat between glowing red hot and no glow. The little propane torches don't cut it and MAP torches typically aren't enough. You need a proper oxygen/acetylene fed torch to make it work right but it sounds like with the tools at hand the best option will be to cut it.
Anyway I went out Friday night and took the Dewalt cut off to it. After I broke the head of my brand new Craftsman 5 ton puller (that sucked). So the puller was stuck on the arm with no way to take it off so I cut two spots in the arm then smacked it a couple times with a little hand sledge and it came right off. Which allowed me to hook my temporary steering up to atleast make it mobile for a little while. Now on to the shackle flip.
