Re: Jeep box upgrade-PICS-and then some...

Hi,

I want to swap out my power steering box on my 1966 Chevelle (small block 327) as it has signifcant "play" in the steering. I have all new front steering and suspension and have adjusted the box, but have experienced no improvement.

Today I puchased a power steering box from a salvage yard, from a 1996 Jeep Grand Cherokee. According to prior postings this should have a KD alpa code. Now for my question, where do I find that code as I do not see that code on the steering box. Is it part of the VIN numer on the vehicle?

Thanks in advance.

Vince

The code should be on a bar-code label stuck to the top cover (with the four bolts and the adjuster in the middle), visible with the box installed.

Thank you, as I was assuming it was a stamped code.

Re: Jeep box upgrade-PICS-and then some...

The steering box I pulled from a 1996 Jeep Grand Cherokee does not have a sticker on top. Is there any other way to determine if this box may be a KD code steering box? Would the other (non KD) steering boxes from that vehicle be acceptable for my 1966 chevelle?

Thank you,

Vince

Re: Jeep box upgrade-PICS-and then some...

You got me there.

All I know is that if it's a '93 (?) to '97 JGC box, it's supposed to have the right ratio.
The regular Cherokees (Sport, Laredo, etc.) are a slightly different body, and, as far as I know, have a less desirable ratio.

The one in the picture is a WK box from a '97.

Possibilities include that the label has just fallen off, or that the box was replaced at some point, in which case anything goes - it could be an exact replacement, only with low mileage (Score!), or it could be the wrong one because neither the parts guy nor the owner of a beat-up Jeep really cared.

Trouble is, it is nearly impossible to actually measure the sweep angle (you'll NEVER get it with a protractor) and the ratio. Turns lock-to-lock mean little, even if the sweep angles are equal, because an old variable-ratio box may have the same 3 or fewer turns, but will be 16 or 17:1 in the middle, where you drive, and tighter at the edges, where you don't care.

I don't really have any good suggestions for you, but someone else here might.
Do you know anything about the car it came out of? Did you actually see it, or did you just pick up the box? Its appearance may give you a clue, but I really don't know how to be sure.

Hi Eric,

Thank you for all of your help. I pulled the steering box myself on Sunday morning from 1996 Jeep Grand Cherokee Limited at a U-Pull-It salvage yard. I still have access to the vehicle. I will probably try and return it for one that matches the suggested list.

Thanks.

I guess I'd say that if the box seemed to match its surroundings perfectly in terms of rust and grime, then it was probably original, but if it looked cleaner than the stuff around it, it was probably a replacement unit.

If you have the VIN, the build sheet with the options codes can be obtained from Jeep.com

Re: Jeep box upgrade-PICS-and then some...

A question for you guys that have done the swap. Does the Jeep box provide less assist than the stock Chevy P/S box? Been driving too many newer cars and find the one finger steering effort from back in the good ol' days to be too light for my taste. A heavier feel would be an added benefit, I believe.

Scott,

I have access to the vehicle so obtaining the VIN is possible. How would I go about contacting Jeep to get a build sheet with the options codes?

Thanks for your assistance.

Im a little confused by this list of parts. Do I need all these high dollar steering couplers or do i need the cheapo autozone #200 coupler?

Also If i do AN fittings i shouldnt need the Lee press in seat inserts, correct?

Re: Jeep box upgrade-PICS-and then some...

Hi,

I am in the middle of swapping the steering box on my 1966 Malibu from an original sloppy box for a late model Jeep Grand Cherokee steering box. I scored a KW box from a 97 JGC for $40 from a salvage yard. I purchase steering "coupler/rag joint" part from AutoZone (31011) for $44.

Now I need to figure out the lines. For the low pressure line I used the return line from the JGC box with a little bending it should work fine. For the high pressure line I will probably buy a new JGC line that has the correct fittings ($20). I need to get the fitting from the back of the JGC pump where the high pressure line connects to make it work. All of the fittings listed in the above file address for various combinations.
