2wd steerung box
« on: Dec 18, 2006, 07:53:25 PM »
I almost bought a 2wd steering box for X over steering but I didn't know if it would work. The deal Im sure had past but not sure. I was just wondering if it would work.

I'm shure its been done before. The only differences I am aware of are the mounting 2bolts on 2wd box vs.3 on 4wd box, and the pitman arm has a different shape/drop.

Gittinit hit the nail on the head.  2wd boxes usually mount with two bolts horizontal and one vertical on the inside of the frame.  They also have a pitman arm with less drop, which is actually good if you want to keep your lift to a minimum.

Also I think the ratios are different than the 4wd ones.

Pick n pull.  I think I've owned about 6 2wd toyotas of different vintages, and only 1 of them had power steering, but I've seen plenty in pnp with ps.

I don't know why the 2wd box would have a different ratio. If it does though swaping the guts into my IFS box might get me some quisker steering. :dunno: Does any one have first hand knoledge of 2wd vs ifs box ratios?

The 2 boxes have the same ratio.

Basic differences are the mounting holes as previously mentioned and the sector shaft on the 2wd is smaller.  The pitman arm is almost flat on the 2wd box and is about 1" shorter than the 4wd pitman which will cut down on your turning radius significantly (I was able to take the steering stops in about 3/16" inch after switching).  Since the sector shaft is smaller, the pitman arms will not interchange.  The taper on the 2wd pitman is also correct for the FJ TRE's that Marlin sells.

Other than that, they work OK.  I had one on my truck for about 6 months.  I used it cause that's what I had when building the truck.  However, I would not do it again.  I developed a leak (not cause it was a 2wd box, but cause it was just wore out) and swapped it for a 4wd box I picked up.  had to cut all my frame plating off and re-do everything  (hack core support, new plates, lots of grinding/cutting/welding).  it was not as much fun the 2nd time.  Do yourself a favor and just use the 4wd box to start with.
