FJ40 and Power Steering suggestions (1 Viewer)

[fj4some]

I was wondering what all power steering systems that you have added to your fj40 that came off something else., or what would fit with little mods? I have access to a 93 Toyota 4 runner but don't want to waste my time if it will not work. I have a F155 eng. in my 72 fj40. Thanks

Ive got the Fj60 kit on mine. It does pretty well. The 4runner box wont work. The piman arm needs to be pointing to the front of the truck.

Most common is a saginaw box, the fj60 box is what I plan on. A box from an early straight front axle toyota pickup or 4 runner (ifs boxes are different) is the easiest and cleanest but it keeps the extra relay rod and center arm and associated rod ends and slop. It provides the least assistance so is only practical for smallish tires. There are others, but are less common.

so is it pretty safe to say that if you want 35 s or larger one should go with Saginaw setup?

Thanks.

Will any of the setup from a FJ62 work on an 82 FJ40?
Not a hi-jack, just thought it was power steering related.

The 60 and 62 series steering box are pretty much the same. The bolt pattern mounting to the frame is a wee bit different between early and late 60 series. The 60 pump is on driver side of the engine while the 62 series is on passenger. I have helped install about half a dozen of these over the last 2 years. Several of these rigs are locked with 35's, and they drive nice on the street and wheel/steer just fine. John

I used a ps box from an 86 fj60, took the axles/steering column as well (tilt lol). All I really had to do to make it all work was extend the intermediate shaft and shorten the relay rod by 1.5". Alternator also needed to be moved to the ps of the engine. I used the column from the 60 so theres a little more screwing around but it wasnt bad at all to set up. Kinda helps that my 40 is still in the garage gettin "built".

Parts list.

1960's nova ps pump
orange45's ps pump bracket/pulley
pass side alt mount (also from orange45)
fj60 ps box/column/axle/tie rod/relay rod
new hp line

Takes some fabricatin but if you could find a 60 for dirt cheap most of the parts would be there.

This is pretty much exactly what I would recommend. 60 series steering box with a Saginaw pump. No butchering the front crossmember to fit the box and you get a pitman arm that is the proper length for the steering arm on your axle.

A lot of this stuff is in the FAQ's section...

That said, I'm running the Sagniaw Steering box from a Jeep J20 pickup, mounted through the driver's side cross member, out front. My truck came with this conversion, so I just cleaned it up. That said, I'm not thrilled with it.

The steering feels a little "numb," and with 31 inch tires, it is so light, I can turn the truck with one pinky. The steering also does not return to center of of a turn very well. I think this is because these boxes traditionally used more that the stock 1-degree of caster angle. I'll be installing shims this spring to see if another couple degrees of caster improves the situation any.

That said, if you are planning on running bigger tires, the Saginaw box has more than enough guts to move them!

If I had bought this truck without the saginaw conversion already done, I probably would have opted for the FJ60 approach. The saginaw boxes are cheaper though, and easier to find.

Anyone with mini truck PS running 35's?

Just curious for some added feedback... as I have 33's and mini PS now

 

[bikersmurf]

Most have said up to 33 with a mini box. However, width, tread design, & tire pressure would likely make more difference than 2" of tire size. A 12" wide 33 AT might even take more force to turn than a 12" wide 35 MT. I'd not recommend a mini box conversion if you're planning on running 35+. But it you're happy with a mini box and 33s, you can likely get away with running 35s.

 

[Toyoland66]

Another issue you may run into with larger tires and mini PS is tires rubbing on the relay link that runs from the steering box to the center arm (I think that's what its called).

It is probably the easiest conversion but solves the least amount of issues with the stock set up (i.e. too many rod ends, center arm, etc which all contribute to sloppy steering).

 

[fj4some]

I am planning on running the steelies with just a regular size mud terrian tire. Probally a 9.50 or a 10.50. If I can get enough steelies.

 

[Bret]

Should have no trouble with a 60 box at that tire size. But if you have later aspirations for lockers and bigger tires AND your going to rebuild the PS box, port the FJ60 box for hydro assist at the same time. It is easy to do yourself, then loosely reasemble and send off for seals etc.

 

[DAD2SIX]

The kits to add a 60 p/s set up are expensive! I found a complete 84 60 for 800 bucks. And am taking the power steering off and installing it on my 1965 right now. (I am parting out the 60 and already made all my money back + some.
Granted mine is a little different because I had column shift. But you get the idea.

I think the Saginaw was the very popular while the 60 series were not around or still fairly new. Now that these can be found they seem to have replaced the Saginaw as most popular. I think the posts here back that up. I haven't done much research on Saginaw but I know they are not all the same. The number of turns was the difference I remember. Another option that hasn't been mention is the one out of a Scout. Not sure how easy those are to find and get parts for.

 

[bikersmurf]

Scout II Saginaw boxes are a decent option. They'll turn 37s with two fingers, mount like a 60 box, and are fairly easy to find parts for. However, they're Older, and parts aren't going to get easier to find. I've not had any trouble finding the parts for the scout conversion.

 

[DSRTRDR]

of course, I vote for the box out o an 80 series

 

[Stumpalama]

Ran stock PS (just like mini-truck) on my 40 up to 35" tires. I switched to 60 PS when I moved up to 37's. In my experience, I would go right to 60 PS at 35" and up.

Stock made me nervous when really working it in the rocks. I was afraid I'd bend one of the many linkage rods.

 

[coinoperated40]

Would the pump from the 60 series work as well or better to use Saginaw?
