Power steering conversion

I'm new to the forum and new to Jeeps. I picked up a '75 CJ5 with plans on upgrading at least three major items. The first being Power Steering. I picked up a used P/S gear box and pump w/ brackets from a '78 model CJ to fit the 304CID.

My question pertains to the steering shaft. WIll I be able to use my old manual steering shaft or can I simply change the lower coupler? Or worse will I have to pick up a complete shaft for a '78 or '75 model CJ?

Any light on the subject would be greatly appreciated.

The other upgrades are going to be front discs and then a 4 speed tranny. Probably in that order.

 

NIce! Your steering conversion will go fine, you will need the coupler though and you can change yours on the end with the p/s one from the 78 cj. The disc brake is a bolt-on also if you get the parts from a 77, 78 cj or knuckles and all from the 79 and new ones. Good luck.

 

Thanks for the info. I'll order a new coupler and hopefully have all the parts together for a "turn key" operation. Yeah right!

 

Would anyone know if a D35 disc setup bolt up to my D30 drums?

 

And ZJs Sparky. We got the great dana 35 in the back of the grand with disks.

 

Aren't all the D35s 5 on 4.5? That could make the swap more difficult/expensive.

 

I would like announce, thanks to input from everyone, that I now have power steering. Although it came after removing a dead snake from the return hose and replacing the pitman shaft seal, since it was leaking like a stuck pig. I must say that the handling of the ol' CJ5 has never been better. All the bump steering is gone and it doesn't wonder nearly as much. I am very happy with the results but have a small issue maybe some of you can help me with. :?

After counting steering wheel revolutions, I am getting about 1.75 turns to the right and about 1.25 turns to the left and the steering wheel is straight on going down the road. Is there a way to adjust this in the gearbox? Keep in mind that I am not 100% sure that I didn't have this problem with the manual setup.

 

Your probably hitting the steering stops on the front axle and not the internal stops for the steering box. You may have to check to see if the piman arm is aligned straight for the box as in the master tooth is lined up when the steering wheel is straight.

 

With the wheels straight and the steering wheel straight, the pitman arm is skewed slightly in one direction (towards the drivers side). To straighten the steering wheel after the installation, I had to adjust the linkage. It is sounding like I should put the linkage back where it was. But if I do this then my steering wheel will be about 1/4 to 1/2 turn off. I believe the steering wheel is keyed such that I cannot simply pull it and reposition it.

Any suggestions?

 

Your column steering shaft is keyed and not splined?

 

I ended up aligning the pitman arm straight which in turn allowed 1.75 revolutions of the steering wheel in both directions. Once the steering was centered I then tackled the steering wheel which was now about 180 degrees off. Since it is a Grant aftermarket steering wheel, I pulled the five symmetrical bolts that hold it down and was able to simply rotate the wheel back to straight and then bolt it back on. This must be a Grant thing which made it much easier to align than expected.

All is goodness now. I get 1.75 wheel revolutions per side, the wheel is straight AND I now have power steering.

Thanks for everyones input and suggestions.
