So I have done my homework and read all the posts on this subject, there are quite a few this website is a wealth of knowledge. Heres is what I have come up with.

1. Find a suitable candidate for a gearbox
Jeep Grand Cherokee box 1993 through 1998 were all fast ratio, bolts right to A body frame. Shouldnt be too hard to find with all the junkyards around the city.


2. A new rag joint (flexible coupler). The following vehicles were produced with flexible couplings that will attach to the new gear:
1977 thru 1982 Chevrolet and GMC C/K (2 wheel and 4 wheel drive) Pickup Trucks
1977 and 1978 Camaro, Firebird, and Nova
1979 Nova
1983 thru 1986 Chevrolet and GMC C (2 wheel drive only) Pickup Trucks.
Again should not be too hard come up with.

3. Hose fittings for the gearbox I understand the grand cherokee uses metric fittings. I also understand Lee Manufacturing sells the necessary inserts to allow your old lines to hook up to the gearbox.

Are there any other alternatives that anyone knows about concerning these hose fittings that anyone is aware of? . It would be pretty sweet if I could get all the necessary parts for the conversion from the salvage yards as opposed to waiting for fittings to be shipped up here.

Thanks in advance

If you dont want to order anything then you could use metric fittings that are originally on the jeep and flair them onto your own hose to work with your power steering. I just ordered a kit from Lees that had a NEW rag joint and adapters. Order it now, by the time you find the box it will be at your house. Also, my jeep box began leaking from the pitman arm shaft after about a year. I replaced it for about $9, pretty easy to do once its in the car. Also, make sure you have a power steering box steering arm.

A: Paid 30 bucks for mine removed it frome a 93. You will need to use the stock bolts from the Chevelle the cherokee bolts arn't long enough.

A: I got the fittings, pump, bracket and remote resivor from Speedway

Thanks in advance

I hope this helps

Just ordered a rag joint and fittings from Lee. Give him a call, he'll hook you up and ship the parts out same day. :thumbsup:

Ok...

First grab the return line from the Jeep when you grab the steering box. The return line is non-pressurized so a basic rubber hose clamped onto the steel line will work just fine. And with the Jeep return line you have the critical metal end fitting for the metric box. Just make sure you get power steering compatible hose. Your auto parts store should be able to take care of you there.

Next it is possible to convert over to all metric O-ring fittings. All of the GM power steering pumps from about 1980 on use a metric O-ring fitting on the control valve. You can pull this control valve out and put it into your old pump. This may be a good idea anyways for pressure and flow reasons.

Now you have the basic issue of finding a compatible all metric O-ring late model power steering pressure hose. I did manage to bend up a hose from a '92 Camaro on my '68 El Camino. But it was not pretty and I don't think I would recommend it. You may be able to match something up from the local parts store if you search long enough.

You could also convert from metric O-ring to AN-6 fittings and then make your own custom steel braded teflon lined pressure hose too. This is what I ultimately did. Best prices I found was at Speedway Motors.

Here's a box is anybody needs one:

Which pittman arm do you use? Do I just get a power steering arm for a '66 and will it fit the GC box?

Yup, you need a power steering arm for a chevelle. It fits right on.

Thanks Brett.

So I've ordered the fittings from Lee. Very surprised at how quickly they arrived ordered on the 16 and received them a couple days ago. I can now use my original lines :yes:

I still need to go get my gearbox from the junkyard its just waiting for me to pull it out the 94 grand cherokee I found at the local junkyard for a whooping $15 bucks.

Question 1. are these fittings just pressed into the new gearbox is it that easy?

Question 2. Will my 1969 pump provide sufficient pressure for the new gearbox?

thanks

As well this rag joint I am assuming is the one that connects to the grand cherokee gearbox that needs to replaced in order to fit on the chevelle steering colume?

The fittings are just tapped lightly into the old box fitting - instruction in the Lee package. Your pump will work fine. The correct rag joint will have the 3/4" dia. splined end and those are at the bone yard on early 80's Chevy vans and pickups. Try it on the box shaft before you leave. Your Chevelle shaft dia is 13.16".

Your '69 pump will likely get the job done but if you are concerned pick up the control valve out of a later Chevy pump. You need the long spring and the piston inside the pump. The maximum pressure is controlled by another spring inside that piston, and they should interchange between new and your '69.

You should not need the outside portion of the control valve that connects to the high pressure hose. It could have different fittings and mainly serves to control flow rates.

I used the Lee fittings on mine, no problem on the return line but the pressure side leaked like a seive fluid poured out fast, the original fittings are supposed to work in the metric box but are a little smaller in diameter when tightend up to stop the leakage the threads stripped. The female threads in the box were still good but it ruined my fitting. I used a metric to AN6 adapter from Russell and made up some nice stainlees hoses, looks better and no leak.

I did the metric to AN adapters and teflon/steel braid hose solution as well. Ran me about $50. Slick thing about this is you can have metric on one end and flare on the other if you want. Try to use a straight fitting on one end of the hose though if you can. I put 90* fittings on both ends which are a bugger to get clocked/aligned right.

anyone else have any problems with the Lee fittings leaking? im going to order mine real soon, an would like to know if anyone else had any issues.

thanks.


aaron

No issues with mine. I dont see why they would be prone to leak if installed properly.

Success at last!!! :hurray: The GC converversion is complete works great. Thanks to all those helped with answering my questions.
In the end I did not use the adapters from Lees manufacturing and went with metric lines instead. Oh well they were cheap anyways.

Gearbox: 1994 Grand cherokee alpha code PD $20
Rag joint: 1979 Gmc pick up truck, these are easy to find in the junkyard, dont know why anyone would want to pay $80 for one. Paid $2 for a used one.
Power steering pump & Brackets: Junkyards are full of these. Paid $20 for all, be sure to get a pump with a metric fitting ie. ones after 1980.
Return hose: 1991 GMC Jimmy
Pressure hose: 1980 Camaro hose from Napa $30. Although I did find one on a 1980 monte carlo in the junkyard, I decided to go new instead. Again get a one with metric fittings after 1980

All the parts for this conversion from experience can be found in junkyards for not a lot of $.

Since I currently have PS, can I just use my current pittman arm and just swap it onto a jeep box?

Thanks

Does this one have too manymiles on it or would you suggest it?:confused:

Thanks,

How did the high pressure hose fit? I'm looking at getting hoses for mine but I am worried about clearance. My pump outlet is close to my headers and is only about 8 inches (straight line distance) from the power steering box fitting. I assume the line needs to exit the pump then bend towards the front of the car then loop back to the fitting? I also am using the GC 12.7:1 box and a 1978 GM power steering pump from a BB pick up.

Jake-
Was your car a non-power steering car before this swap? I am thinking about doing this but wondering what a hassle it will be because mine is nonpower right now.
Thanks

not hard, swap out the box, get a ps pump and brackets, and a ps pitman arm. straight forward, and well worth it.


aaron

Iowacar, My car was a 6 cylinder with power steering but in the end I did not use any of the original gear except for the pitman arm, everything was from the junkyard. Oh and the pressue hose from napa. All in all a very worthwhile swap very easy to install and cheap. The only hiccup was tracking down all the parts a bit of a treasure hunt but i enjoy crusing the junkyards some may not.
Vince I have hooker headers for my 350 clearance was not at all a issue with the 1980 camaro power steering hose fits great. Ill post a pic or 2.

some pics: I filled in the Alpha code PD with a black marker it was fading a bit

That 1980 Camaro PS pressure hose looks like a pretty good matchup. Nicely done. :thumbsup:

does the camaro hose have metric threads on box end, and std size on pump end? or did you have to use adapters?



aaron

The Camaro hose is metric on both ends. You can use a later control valve outlet fitting on the PS pump in place of your older fitting to be compatible with the hose.

Do Lee Manufacturing have a website or e-mail ? I can only see references to fax and phone. I am in the UK and it would be easier to contact via the web or e-mail.

What are the prices for the

Adaptors
Rag joint

Thanks

Mike

Does anyone know if this Jeep Grand Cherokee box is the same as the later model GM truck and SUV Delphi 600 series "rack and pinion valving" box?

Has anyone use the 600 series box and what vehicles and years do they come in? Thanks!
