1973 power wagon crossover steering
« on: November 27, 2012, 11:43:14 AM »
First, i have a 73 power wagon 3/4 ton. D44 disc brakes up a front. 6" lift springs. Power steering.

Looked through lots of articles and found some good info on crossover steering. But now im left with some unanswered questions being that i drive a 73. So questions i have.

1. Looking to buy a crossover steering kit from sky manufacturing. Any thoughts on quality?
2. Wanted to buy a new borgeson steering shaft for when i relocate steering box. But their website only lists for 78 and up dodge trucks. Is there a difference for a 73?
3. Also need a new steering box as mine leaks pretty aweful. Can i use the autozone/ oriely brand or should i purchase one from somewhere else? And will it be compatable with new steering shaft?

Some help in the right direction would be VERY much appreciated so im not buying wrong parts.

Thanks in advance.

You are going to need a new steering box either way for crossover since you have the old style steering box with the swing arm and you will need a normal rotation one like on the later '70s and up trucks.  As for the steering shaft, there is not much point in swapping to a Borgeson since the old style steering shafts do not have the problem of the newer style's worthless joint.  GM style joint used on the older trucks is much better.  Naturally when swap steering boxes everything goes out the window so you may end up with something custom in the end.  As for crossover in general, check what axle you have and look to see if it has flat top knuckles.  If you have disc brakes up front, wither the axle was swapped or you have a very rare truck as I have yet to see a '74 or earlier model with the optional disc brakes.  If you have flat top knuckles you should be ok to have the passenger side machined flat for crossover, if not, you will need to swap one on.

I want to say the axle is stock but the brakes were converted. I do have flat top knuckles so i can get it machined.  As far as the new steering box, can i order say a oem replacement 78 or 79 from an auto store then bolt up to the 73 frame? If so the new steering box should be compatable with crossover steering yes?And the stock "old" style steering shaft i have will have to be replaced anyway when i relocate to the 2wd position correct? So i should buy a new shaft

I'm not positive that the newer steering box will bolt onto the old frames but if not is should just be a matter of drilling the holes in the right place to mount it in the 2WD position.  It's very possible that is could bolt in, I've just never done it or seen it done yet.  Depending on how it's located you may or may not need a new steering shaft, or you may just need to lengthen or shorten one, regardless of the type of shaft.

Inverted flare fittings on boxes up to 1979. 1980 and later use the metric O ring fittings.

Pump and lines need to match the above 73-79 or 80-93 guidelines due to metric o ring vs sae inverted flare.

The exception of course, is if you converted to JIC37/AN lines. Then can use common adapter fittings, but will pay more to make your own hose. I am not aware of anybody making or selling a conversion hose, so having the matching pump and lines is likely more your style.

So sounds like i need the pump, hoses and mounting plate asto well. In that case would the 93 pump bolt up to the motor at least?

Yes. Get the bolts and nuts as they are also metric.

K last question before i pick up the parts this weekend. The donor is actually a 90 4x4 w250. Will grab the power steering gear box, power steering pump, hoses and hardware. This should fit my need for a new borrgeson steering shaft as well as crossover steering for my 73 yes?

Appreciate all the feedback from you guys. Making my job a lot easier.

appreciate the thread links. i have read through them already. good info. questions i have are not about install, that i can do. i have a 73 power wagon so i will need a late model steering box in order to do the crossover because early model boxes have the output shaft facing the wrong direction. im wanting to make sure if i pick up a power steering pump and gearbox off a 1990 w250, that everything will lineup as far as mounting it to the frame, and pump to the engine.

The steering box will mount up using my frame boxing kits & the steering box will not rip out or crack the frame like the X over does with the stock frame setup. A 90 steering pump should replace yours.

remember to order your steering shaft for a 2wd truck since the box will now be located closer to the firewall......

It won't matter since he will still have a early '70s steering column so none of the common Borgeson and similar shafts will bolt in.  He will have to have one made or just modify the one he has since there is not much need to upgrade it.

So assuming i get this 1990 steering box mounted to my frame, i cant get a bogeson steering shaft to fit? Could i cut and weld my current early 70s steering shaft to fit to the 1990 box? Or is there an issue with the connection point?

The Borgeson shafts were made to correct a design flaw in the later steering shafts that your earlier model does not have.  You could probably make a Borgeson shaft work but there are a few issues.  The first is the rag joint on the earlier models is at the steering box and the steering joint is at the base of the column.  This is the exact opposite of the later models and may cause some issues getting a Borgeson style shaft adapted.  I have never compared the splines but it is possible they are the same as later shafts but it's just as possible that they are not.  The length is the next hurdle since no Borgeson shaft is made for the earlier models and you are going to need an odd length anyway since you are swapping steering boxes and moving it's mounting.  So it's doubtful that anything you buy will bolt in exactly right and you won't be getting much improvement over your current steering joint, not $200 worth in my opinion in any case.  Now with all that said the shafts do collapse and the length is sort of variable but according to Borgeson at least, the length is specific to the vehicle.  If you look at the stock shaft, the length is only variable about an inch or so in the joint and what little deflection you get out of the flex joint.  So you could consider the Borgeson style shafts a bit overkill since most I have seen have a decent amount of slip shaft in them and it's possible you could easily adapt one to work if you can get the splines right.  Again, I have not done it so I don't know what issues this will pose so I can't, in good conscience, recommend it.  Personally, I would just shorten or lengthen the shaft you have since it has none of the later design flaws and it's the cheapest route to go.  As long as you or whomever you have weld the shaft is actually a competent welder, you shouldn't have any major issues going that route.  Just my .02

What i done with mine is use a 79 steering column,Borgeson steering( box bolted to the stock 2wd frame hole location,Borgeson steering shaft,and the pump.Yes the newer box will bolt to the older frame.My frame was a 2wd and i made it a 4wd.I used the borgeson box because i ran hydroboost with my diesel setup.The boxes you buy at Autozone and other places are trash.

So the 90 donor has fallen through. So i think ill buy a new 78/79 gearbox and save the extra trouble of swapping a new pump as well. Question now though is that replacement 73 boxs say they are 32 spline input where as 78/79 are 26-29 spline input. How can i adapt a newer 78 box with 29 or so splines to my steering shaft which appears to have 32?

Could he use a 73 2wd box?  Would still ahve tomod the steering shaft but the hoses should bolt up and box fits the frame (2wd location for crossover)

what you can do for the problem of swaping different years of steering boxs when you grab a steering box from a junk yard grab the pressure line and the fitting for it from the back side of the pump, you will need a 1 inch wrench for the fitting also grab the return line as well.the fitting on the back side of the pump should fit every year of saginaw power steering pump your playing with.this way you never need to worry if the pressure line is the oring style or the flared one.oh one other thing make sure when you remove the fitting from your steering pump you dont lose the pressure regulator,it has a spring behind it and sometimes like to pop out and hide in the engine bay lol
