another power steering question

[jeeper]

I've decided it is time to get my truck set up with power steering and power brakes.

I read some posts on this site that describe using a steering box from a fsj. I've also seen some discussion about using the hydroboost from an Astro van.

Today I found both items at a local salvage yard and brought them home.

I started with the power steering box because it is supposed to be a bolt on operation. Well the box is but the stock pitman arm is not in my case. My steering box came off a 1985 Wagoneer. The box fits the frame perfectly but the pitman arm is a drop pitman arm. Also the shaft on the power steering box is smaller and the hole for the tie rod end is smaller.

Anyone have any suggestions?

Here is a zone post with conflicting info on what year arm to get. Power steering

I dont know the thread pitch on either the drag link end that fits the FSJ pitman, or the drag ling end on the 715 knuckle. If they are both common thread pitch, like the GM 7/8-18, you can buy the 7/8-18 R-L inserts, and a piece of DOM tubing and have them TIG'd into a conversion drag link.

I am doing a variation of that with GM parts for my axle swap.

Thanks George. I found that one too but it says I need a pitman arm from a 80-91 Wagoneer. My box and arm are from a 85 Wagoneer. The Pitman arm on the box is about a 4-6 inch drop and has too small of a drag link hole.

Is it possible I have a drop pitman arm from a vehicle that had a lift?

I spent about an hour trying to get the arm off the box yesterday and failed.
The stock arm came off the manual box just fine though.

The stock pitman arm on an FSJ box is nearly straight, or has maybe an inch of drop at the most. It sounds as if you ended up with a drop pitman arm intended for a lift kit. Not sure why the difference in the tie rod end hole though.

I agree with Randy, sounds like an aftermarket pitman arm

supposedly this is the correct pitman arm for the FSJ box and the M715 drag link. I cannot confirm this myself but it seems correct.

Also as far as getting the old arm off, heat will help but you have to be careful not to cook the seals in the box. Worst case, cut a slit in the pitman arm towards the shaft and try that, or just cut it off...
