  • Found out some new steering box interchange info

    Sorry it has been awhile since I have posted over here. I have kept up some, but mostly just reading

    Anyway, we have know for some time that that 82-01 S-10 steering boxes are an excellent replacement. Then some guys wanted something faster then that and have been hunting the little more rare 96-01 ZQ8 or 87-92 Z28 steering box.

    This is the new info, 92-98 Grand Cherokee's use a 12.7:1 steering box and it is a swap for s-10's. If this will swap on the s-10, this means it will swap on the the FSJ.

    Now you can have that fast ratio steering you have wanted, but in something a little more common to get your hands on.

    I saw that when I was researching before I installed a S10 box. Attached is the link with the info. I wasn't as interested in the fast ratio as I was in having more road feel.

      I 've seen this in an article.

      It claimed the Z box was stiff to steer with oversized tires sitting still & a challenge off road. I don't do that much off roading but it would make sense in rock & such. it's also not a solution on anything but later models. unles you want to modify your fittings.

      If you can't make it better why waste your time. No use repeating the orignal mistakes. I'm to old to push it that's why.

          I don't mind it too much. Feels pretty plush IMO. Wouldn't mind it being a little faster off road, though

            Would all the hose fittings match up between the ZJ and the S10?

                No. The firmer feel of the S10 box translates into HEAVY steering when the going gets tough off-road. I am looking to swap the S10 box off my J10 for something with more assist... e.g. a J20 box. I have a J20 box on my M715 and it is a DREAM to steer 11R16 military tires. My brother thinks it has too much assist, but there is no such thing on an off-road vehicle that gets driven over boulders.

                  There's a lot of folks out there like the original steering. I for one don't. I don't utilize mine in conditions that warrant rocks or ruts that would make it difficult. I've been in these positions but haven't noticed any issues. Towing & highway driving crosswinds are less of an issue. Quick response lane changes are a +. With all of my other vehicles have R&P steering, this is a little more to my prfference. There's no right or wrong here. You might possibly change your mind if you were to try it. I wouldn't have mine any other way. But it is just my preference. I had no idea until I drove a chevy truck that was modified. Another advantage its it's so much easier to back a tailer & pull one. Whatever slack you have in your steering is cut in half.

                    Thanks for the info -- I need to shop for a steering box soon. One thing I dislike about the Wagoneer's highly boosted steering is that it makes it tough to feel what the tires are doing in the tricky bits. It's not helpful when scrabbling for the last bit of traction to have steering that feels like a video game. I had an S-10 box on another FSJ with 33s. While it did require more effort, it was still easy enough to steer that a little kid could drive it in the rough.

                      There is also some debate about the later model GW's having a stiffer feel. I maintain that the '86-up GW's have a stiffer steering more akin to the afformentioned S10 box. This is based on first-hand knowlege that my former '87 did, even after installation of a reman box, and my '76 has the "Cadillac" easy steering, and based on reports by others here. (heresay I know, but I trust you guys)

                        Mine is an 80 3"body lift. 4" spring lift Upgraded sway bars. Gas charged shocks 33x12.50x15's. Do all that with a stock box & it's like your driving the SS Minnow.

                          I was thinking of swapping in one of the Delpi-600 boxes, with the R&P spool valve setup, there was a guy on ebay that seemed to have or could get the various options (ratios, feedback feeling ...) but they are not cheap.
                          The old boxes are pretty programable as far as road feel vs. ease of turning by swapping the torsion rod (Caddy ones are soft, Z-28 Camaro's are hard , in general) as well as having lots of ratios and a couple bore sizes to play with, so you can do a lot with the old box if you are willing to dig in a little.


                          BTW (nice link)

                            For me, the only FSJ I've owned that had too "plush" steering was my 86 Waggy. I could steer it all day long with my pinky finger. And I didn't like not feeling the road. My 81 cherokee w/t with 31s (factory size) and slight lift was the stiffest but you could feel where the tires were going when off road.

                              I've driven 83's, 85's and 88 FSJ's. I could not detect a difference in steering. <shrug>

                              And I'm one of those that likes the stock steering control (or lack of?!), too.
