I've finally got my arse into gear and picked up a power steering box and pump out of a FJ55 (i think) to convert my fj40 to power steering. Does anyone know an easy way to get the pitman arm off the steering box? I've got the giant nut off but it dosent look like the arm wants to budge.... help <IMG SRC="smilies/confused.gif" border="0">

I use a three jawed puller. You have to make sure the feet that hook onto the metal are clean and sharp. Also a little heat on the Pitman arm is req'd if it's never been off.

3 jaw pullers can work, but I would avoid them. I tried to use one on a really stubborn box a year ago and it kept slipping off, and when I did get it to grab hold,... I blew up like a granade! <IMG SRC="smilies/eek.gif" border="0">

Definately use a pitman arm puller. and even with one of those you cant just wrench them down on a tough arm. they will blow too. I like to use heat only as a last rersort. paranoid of frying the seals.
I do this,....spray a little pen lube on it the night before, the next day, Tighten the puller pretty tight on the arm and get a good size hammer (3lb) and wack the arm arond the base, away from the box. tighten a little, hit it a little,.... and so on.

if that dosent work, you must have fawken froze up mofo. then throw a little heat on that arm with the puller under tension.

It WILL go eventually. belive it,....or not <IMG SRC="smilies/biggrin.gif" border="0">

I really got tired of messing with pitman arms, heat, pound, squirt,turn, and do it all again. Finally the thing will pop off. What I did to ease the job was to fashion a pitman puller of my own. Using an old drum puller, the kind with a 1 1/2 bolt in the middle, I made two u shaped brackets from 1/4 plate that slides behind the pitman. Each bracket has two hole drilled in the side. Slide the brackets together till the hole line up, put a 1/2 bolt through the brackets and back to the puller. Bolt the 1/2 inch to the puller. PUt an air wrench to the 1/1/2 bolt on the puller and the pitman comes right off.

Yep i have a puller for steering wheels similar to that as long as you pull on the arm equally watch puttng much heat as you will end up cooking the seals in the box

here is a dumb little tip for using any puller.

wrap a rag around the arms or base of the puller. It deadens the flying chunks of metal if the puller blows. And they blow! <IMG SRC="smilies/biggrin.gif" border="0">

I started doing this when trying to remove a pitman arm with a three jaw puller a while ago. A good size chunk of the arm stuck in the wall next to me when the puller blew <IMG SRC="smilies/eek.gif" border="0">

I found that by spraying PB Blaster (penetrating catalyst) on a day or so before a few times really helps. Also to prevent from blowing pullers I fount that the quick zap of a impact wrench usually free's the arem and keeps the puller intact. So far I have done this with 6 arms and haven't broken on puller yet. When I was using manual strenght via a longer ratchet or breaker bar I went through 3 pullers on the first arm!!

My three jaw puller dosent fit behind the pitman arm, so im using a two arm puller and im getting no where fast. I've sprayed and resprayed with WD-40 and i think im going to take them to my friendly mechanic and get them attacked with a hydraulic press. It has been a very frustrating weekend <IMG SRC="smilies/mad.gif" border="0">

I have found that on the really stubborn pitman arms (when using a proper puller) that giving the end of the puller draw bolt a whack with a hammer will sometimes free it up.
If the pitman arm is what you need (and you don't care about the steering box) try removing the top plate (the one with the sector shaft preload setscrew and locknut) and press the sector shaft right through the pitman (backing the pitman up against the steering box) this manouver will likely trash the sector shaft seal though.......
