<< Hey all I have a 92 extra (all stock), and want to install power steering
 to a truck that came w/out it.  what do i need to do out of the ordinary.
 I know about the brackets/pump/belt, but wonder if the gear box needs
 to be swapped.  Also what other than a toy truck can i scavage the parts
 from.
>>

I did this addition to my 81 4x4 pickup. Yes the steering gearbox needs to
be replaced.
 In addition.  I needed to get a fluid cooling tube thats runs behind the
grill.  The crank pully on my truck was a single row pully.  On the power
steering equipped trucks it was a 2 row pully. Actuallly I just bought the
second half of the pully from a junk yard and it bolts onto the existing
pully.   I also needed to get the resivoir that sits on the side of the engine
compartment.  On american cars the resivoire is part of the pump.  A box full
of hoses. All the hoses I used were from the junk yard, except for the output
side of the pump.  This is the high pressure hose.  900-1000 psi here!!!  I
opted for a new hose. For obvious reasons.   

REMEMBER! I have an 81 pickup.   I have seen a more recent 2wd toy and it had
the same basic setup.

Have fun!  Its brought a whole new level of satifaction to driving my beast.
On & Off Road!

Kurt:

I did a power steering swap in my brother's '91 4X4.(4cylinderEFI) It was
pretty easy.

I purchased a used "kit" from Toyota Truck Recyclers in Rancho Cordova,
California. It was about $300, but this was a few years ago. The kit had a
6 month warranty, not bad for used parts!

The kit came with everything you need: pump, steering box, fluid reservoir,
fluid cooler, brackets, idler pulley, and the "add on" pulley that bolts to
the crank pulley. They even included a crusty used belt, though I would
replace all the belts when you do the swap. Don't forget that you will need
some vacuum hose, probably about 4 to 5 feet, that runs from the power
steering pump to the EFI intake manifold. This allows the EFI to raise the
idle when you are turning the wheel while idling. Find a similar truck with
power steering to locate exactly where the vacuum lines go. It makes it
much easier.

The toughest part of the installation is getting the steering input shaft
(from the steering wheel to the steering box)to the proper lenghth. There
are splined ends and u joints with pinch bolts, one near the box and one
under the steering wheel. You may need to loosen the pinch bolts at both
ends and slide the splines out a little to make the shaft the right length.
You may also have to remove the steering wheel and re-center it. Check the
bearing in the idler pulley, and if it is in questionable shape, replace
it. Check all the power steering hoses, as now is the easiest time to
replace them. Don't forget power steering fluid(or ATF)!!

Well, I am getting out of breath.. I think that was everything. There are a
few Toyota salvage yards in California that I know of, and many of them can
ship you the parts. If you want their phone #'s, email me and I'll track
them down.
