How to ID a 2WD Steering Box for x-over use - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Oilbrnr · 08-21-2009, 05:20 PM

So after putting a 4" lift on my K5 earlier this year, I'm getting closer to biting the bullet and doing a x-over steering setup on my D44. A fairly expensive piece of this conversion is the 2wd box at ~$200 not including a core.

I got our original family business '55 GMC delivery truck back from my cousin's x-husband over a year ago, literally in baskets, boxes and various forms of dis-assembly. I don't exactly know what the dude had planned for his restoration but he did put on a new GM PS box as seen in this picture:

I plan on returning the '55 to the original box so I won't be using this one anyway. Is it as simple as looking at the sector shaft to ID it?

The difference is in the sector shaft.On a 4wd the pitman arm slides onto the splined shaft with a nut and bolt holding it on through the side.The shaft is keyed,like a 1/2 circle,on the side for that bolt.On a 2wd the pitman arm slides onto the splined shaft with a nut threaded onto the end of the shaft to hold the arm on.The boxes (cases) are identical in appearance.The arms are absolutely different and not at all interchangeable.

Also the 4wd swings the pitman arm from front to back when on the vehicle, and 2wd swings from side to side.

So a threaded sector shaft is what I should look for. Thanks.

Yes.There`s no mistaking it.

You can get them at the junk yard for $25. So if you have the wrong one, save some money and get one there. Just be sure the lines are the non o-ring type. Put your money into the steering arm, hardware, and machining the knuckle.
