power rack and pinnion?

Hey everyone did a search and didn't find what i was looking for so here i am. I have a 1949 ford f-1 pickup and have decided i want to keep my straight axle but would like to add a power rack and pinion to the straight axle. First question is, is this possible and if so how do i go about installing/ mounting it to the straight axle?

I really don't think it will work,And don't think I would try to make it work. Maybe someone here might have tried it, and it worked,But I don't think so. I have never seen it done.

I really don't think so,But I'm not 100% sure.

Why wouldn't you want to go to IFS. Man I had a 48 Chevy that I put a clip under,That thing drove so much better,Disc brake's,and power steering,Night and day difference...

well at the moment to go to the ifs i would have to redo my motor mount. If i had the money to put the ifs in and redo everything i would but i feel it would be a step backwards at this point and time. i have disc brakes installed and thought a nice power steering set up would be great plus i need to redo all the steering to make room for my headers.

this is a kit i found but this is another kit that i found that i could use instead

What you are proposing has been done with good success. Mounting the rack to the axle is fairly straight-forward. Measure the amount of steering arm travel you currently have or would like to have, and the overall length and select a power rack that will get you there. Some racks (like Mustang II) only need two holes drilled into the axle and the unit will bolt on. Other styles can be installed with simple to fab mounting plates. Use your imagination. Bump steer is not an issue because the rack moves with the suspension. Which brings me to the tricky part. You must install a slip joint into the steering linkage to allow suspension movement. A small driveshaft slip joint for a two piece driveline works well. Go to a driveline shop or a heavy truck parts store and see what they have. Make sure whatever slip joint you install has enough travel so it cannot slide apart at full droop of the front end. Once you have got that far, connect the rack to a P/S pump and you are home free.

A bit of work, yes, but it should be able to be done relatively cheap.

Sure would love to see some picture's of it done then,Sure seem's to me it would put the steering shaft in a bind.I know you said a slip joint,But It would be on the wrong angle to work right.Well all I can say,Is if he does this to his truck,Good luck.

This may not be power steering but the owner says steering is easy and it seemed to me when he allowed me to try it at a stand still. He had a 38 Willys PU with a big cast iron block hemi. He took a Unisteer from Maval. They are designed to replace a cross steer vega box. He shortened the rod and mounted it length wise along his frame so that it would push and pull on the steering arm. I have been thinking of copying this design and have also wondered if a power steer rack would do the same thing by cutting one side off. Just not sure if a power steering rack is a 2-way action.

You are right !!! I set ''NO'' Limit's on myself, I'm sure I have proved that enough here.. But I do draw a line on safety..You seem to follow me around a lot I see,And enjoy bumping heads with me. Well I did say I didn't see it done before..And I do stand behind not telling anyone to do it.Sorry I just don't think it's a good idea.. And if he want's to do it,That's him,Like I have said before, good luck. I'm done here..

Maybe you would explain to us what is unsafe about this setup?

By the way, the only folks I follow are the ones about to go another lap down...

Well first off,A slip joint was not designed to move in and out all day long,It was designed to collapse on impact only.

And as far as this goes,Well let's just say you aren't worth answering,I'm done talking with you,I'm sure I will see you around,Since you like to try in stick your foot in my mouth every time I open it. And you can respond to this if you want,I'm sure you will !!!! Like I say before I'm done playing your little game.

Andy ,I am sorry but that is the silliest thing I have ever heard. Are you trying to get this poor fellow killed? Mount the rack on the beam axle? slip joint? Also drilling a beam axle is very tricky so as not to cause a week spot as it takes a beating. Wow I thought I heard it all but damn! Anybody plz speak up if I am wrong but my gut and experience says otherwise.

Oh by the way a slip joint only works in a straight line back and forth. What happens if he goes in a ditch and the axle goes at a angle? Also I dont think you can find a rack with the steering shaft that is coming out if it straight,most are at an angle. I want to see pick of this if it has been done. Tim

And if I was to do this,I would think that a Cross steer rack and pinion would be the best way to make this work.Not a rack mounted to the axle.Sorry.
