I plan on updating the 66 to the quick ratio (12.7 to 1) using the 92.5 - 98 year, Jeep Grand Cherokee.

Are all Jeep Grand Cherokees form those years going to be the same?

The problem is, the yard will not let me take it out, they just plunk it down on the floor in front of you, and say here it is. I worry about them giving me one which will work,(bolt up) but is not the correct quick ratio 12.7, with the 43deg 45min travel.

So, is there any way to ID this thing, laying on the floor in front of me? Like numbers on it, or number of turns or something?

Thanks Bill

right on top of the steering box there is an aluminum cover. on this cover should be a white sticker with a bar code, a part number and a 2 letter code. the two letter code will identify it.

you are looking for the steering boxes with the following codes.

AL
BT
JH
KD
WK

i swapped from manual steering to a WK box and man i gotta say its the best upgrade i have done to this point. its a totally different car, i love it!

hope this helps

There was only one gear used on the 1992 1/2 through 1998 Jeep Grand Cherokees. No optional gears. So as long as the year and model of Grand Cherokee is correct, you will have a 12.7:1 gear.

You do not want the steering gear used in the later Grand Cherokees (even though it is a 12.7:1 gear as well), because it has a different mounting bolt pattern and will not bolt up to your Chevelle.

Thanks guys, thats just what I needed.

I read somewhere that NAPA has the adapters in their weatherhead line, so I can use my existing hoses. Do you think these are the same adapters that Lee Manufacturing sells?

Thanks bill

I've never used the NAPA adapters, but I have used the ones that Lee Manufacturing sells and I believe what he sells, he makes himself. They are machined piece of aluminum that changes the hose seat to accept your original hoses.

The adaptors from Lee where around $13 all together shipped last time I ordered them.

Just scored a jeep grand cherokee gear for $30 through Carparts.com. The yard is just two miles from here. It's out of a 98. I will pick it up after work today. I hope it is the right one and the code WK or BT will verify it.

I will most likely go with Lee Mfg for the rag joint and adapters. Does anyone know what the cost of the rag joint will be?

Thanks bill

Does the box have to be from a Laredo or a Limited (with the speed sensing steering)? :confused:

The boxes from the Jeep Grand Cherokee's that we are looking at come from 1992-1998 Jeep Grand Cherokee (ALL).

I am not aware of any speed speed sensing steering on any of these years Grand Cherokees, but I could be wrong.

I know of a few extremly highly optioned Jeep Grand Cherokee's from this era and none of them that I know of have any type of speed sensitive steering.

When I was searching on carparts.com they had the speed porportioal choice for the 96 year only. I don't know what that was all about.

I picked up my gear after work tonight and it had the BT code on it, so I guess I got the correct one. Now to order the adapters and rag joint from Lee Mfg and I am all set. Can't wait to feel the difference, I hated the stock set up, it always wandered back and forth on rough roads.

Thanks again, bill

I was wrong the other day when I said that there were no optional gears for the 1992 1/2 through 1998 Grand Cherokees. The 1996-97 Grand Cherokee did have optional EVO (Electronic Variable pump Orifice)variable effort steering. That system did have a special gear with a more sensative steering valve.

The way EVO worked is that it electronically lowered the flow out of the pump as you drove faster on the highway. The steering became less sensative at the lower pump flows. At low speeds, the pump was returned to full flow and your steering felt light because the valve was quite sensative to flow.

If you install a gear that was designed for EVO into a car that has a standard full flow pump, your steering on the highway may feel a bit light and it might feel darty when trying to keep it in a straight line.

The bad news is that I don't have the broadcast code(s) for those gears. I will try and make a visit to Delphi Saginaw to obtain those codes in the near future.

Thanks for clearing that up Jim. It had me confused when a friend of mine told me his Grand Cherokee had speed sensing steering...thus I had to ask the experts ;)

Nothing like having our own resident engineer from Saginaw on this board :D
