M886 power steering help

[44CCKW]

I installed power steering on my M880 last year .No problem ,Everything went smooth.I decided to do the same to my M886 today.Everything bolted right on.BUT,When I went to test it before putting the wheels back on I noticed it was steering backwards.When I turn it left it goes to the right and when I turn it right it goes to the left.I have full steering motion side to side,It is just backward.Now I'm thinking this may be because the steering box is from a 2WD truck.Can this be fixed?Or do I need a box from a 4x4 truck??

Was the pitman arm originally facing the opposite direction?

When the steering box was in the 2WD truck it was bolted with the out put shaft facing down.When I bolted it in the M886 the out put shaft is facing out toward the tire.I had to change the arm from the box.The 2wd has a flat arm and the M886 has a bent drop arm.

72 - 77 2wd have standard rotation, and 4wd have reverse rotation boxes, and almost bet that you feel alittle foolish right now, lmao! trust me i have done far worse lol

Interesting,Can the rotation be changed?Or is it just easier to get another box??

and the worst part is that they look identical
Seriously, Same dang Saginaw housing on both std & reverse rotation boxes!

another box, id say its internals and worm gears, cheaper and less mind boggling to get 4wd one, i just got a 74.5 year ps unit and axle with lock out hubs, just swapped whole thing last weekend, i heard chevy had same style box but unsure

The old chevy 4wd have straight rotation and looks identical to the dodge box I found that out the hard way once when I was looking for a box in a junkyard, I bought it and realized it at home before I installed it when I put it beside my old dodge one and spun the shaft and noticed the pitman going opposte direction

ironbulance, but does chevy(GM) use different for 2wd as 4wd? and yes bob its a havoc if you come across one unbolted and laying about i guess there has to be a stamp or some thing or possible marking to look for for ID, and other than i guess testing your self is only sure way, sorry 44cckw for your luck!

It was a while ago but I think I removed it from a 74 or 75 4wd model

Thanks for the tip on this. I have an M886 and have been considering upgrading to Power steering and have been looking at a donor truck that is 2wd. That would have been a bugger to get it installed and found that it didn't work right.

Reverse steering; AH, the memories that brings! When i was maybe 26 I built a "tractor" out of a metal frame that was lying around, the rear axle and two transmissions out of a Rambler, and a Dodge straight front axle. I mounted the steering box the most convenient way. When i drove it the first time, I found I turned the wheel left to go right, right to go left! Oh well, I wanted to drive the tractor, not fix it right away. No problem around the farm. However, we used to go to a large pond about a mile down the road to skate. I decided it would be fun to take the tractor, 20' of hay rope, and a large enameled Coke sign to the pond. A couple of guys could sit in the sign, be pulled by the tractor, which would then spin out and play crack the whip with the guys in the sign. It was a lot of fun! However, to get the tractor to the pond, one of my friends said he could pull me with his car to save my fuel for more fun. I told him to not go over 10 MPH because I would be busy given the steering problem. Of course he decided to give it more speed, up to 30 MPH. I am bouncing along on this thing, telling myself constantly "right is left, left is right" to keep it going straight until we got there. I was too shaken after we arrived to really give him what I thought he deserved for doing that!

Did it work out?
Here is a pic of someone from the Netherlands who did the same thing, a 2wd box instead of a 4wd.
But they fixed it.
