    I went to Napa and bought a reman waggy box (I think I said 1984), it was about $160 with a $150 core charge AND was in stock. Pretty much a direct bolt in, just drill the 4th hole.

    joined the cracked mounting ear club this week (could have happened earlier, but only found it this week due to trying to figure out why my 93' drove like ass)


    Sucks that PSC sounds like a waste of money for a frequently driven rig

    Due to this write up I'm going to try a YJ box swap instead since I already have a rebuilt one & it will upgrade me to 4 mounting bolts & a consistant assist ratio (plan to drill it for hydro assist also)

    This totally sucks...I was looking into the PSC because I thought it was going to be a worth while upgrade but after reading this I will just get a Waggy box.

    Let me get this straight, I need a Waggy box from a 1980 or newer Wagoneer? With O-Ring style what? I am new to this steering box upgrade stuff so any input will be greatly appreciated. My 97 box is toast, I tried adjusting it and its nothing but slop on the road I can turn the wheel probably a complete half turn before anything happens...not good

    Quite a few of the XJ guys are running Durango boxes. Still only 3 bolts but the piston has a bigger bore. Anyone here tried one?

    1980 or newer Waggy with the o-ring style fittings on the fluid lines so you can use your stock fluid lines with the box.

    Why only a month? Any reduction in turning radius?

    I was under the impression that the Waggy/J10 boxes were NOT the real deal unless you got them straight from a J10 that had an OEM steering box.

    That was the J20 boxes I believe, which are better than a Waggy box if you can find one.

    Yeah the J20 box is the one that's hard to find, most auto part stores will give you the Waggy/J10 box if you ask for the J20.

    I just picked up a waggy box from NAPA as well. They told me the std waggy is still a 3 bolt setup but the 85 grand waggy is a 4 bolt. I will get it installed this week and report back. I have got 12 in of snow and just believe I want to go out to deal with it today. My stock box is WORN OUT and leaking bad. It drives like a snake going down the road. I can not wait to get this done. I just got back from a 3 week trip and at least need a days break. I will report back this week. Later...Clint

    The gear box on my jeep is leaking pretty bad, and it's a little sloppy at this point. Two questions for you guys:

    Is the waggy box that much better than the box from my 00WJ?

    Is the waggy box a direct replacement for my 00WJ?

    OK, Got the new steering box installed and it works great. I have not added the 4th hole mount yet but will get it done very soon. When I pulled the pitman arm... The guts fell out of the old box... Man that thing was a lot worse then I knew.
    The box I ordered from NAPA was part number 27-6528 for a 85 Grand Waggy.
    Bolted right in. everything was the same except it has the 4 mounting holes and I am told that it is a much better (stronger) box. I have a 94 ZJ so I am not sure what esle it fits but it sure wirked great in the ZJ. Hope this info helps some of you out. Later...Clint

    Clint, is it any easier to turn the wheels with the new box?

    EDIT: Also, if you don't mind me asking, what did the new box run you? Can't find it on NAPA's website.

    Yea I think about 160...My wife picked it up while I was out of town. The steering is very easy but no leaks now and the steering slop is gone. Man it was all over the road. It's nice to have some good steering again. Be sure to go through the correct purge to get all the air out of the system. Later...Clint

    After thinking about it awhile, is it possible that the PSC box was simply destroying itself turning locked big tires with an assist cylinder?

    All that extra turning effort is directed straight at the sector shaft bushing/bearing, so maybe whats so great about the PSC is also causing the problems & those who have no problems are turning smaller tires or not wheeling as hard?

    I started a thread because I originally had a plan to have PSC make a box for me, but seeing as how it is as expensive as it is AND that is seems to have problems, I wanted some feedback on what's up with the WJ stock steering box. It seems to be superior if some people are wheeling 39's without issues.

    Does the steering feel easier then the when you had the ZJ box?


    I installed a reman 4bolt YJ box with Kevins steering brace on my zj this weekend & everything worked out fantastic as well as massively increasing the stability & control on the highway

    But the damn thing is harder to turn the tires then the ZJ box was?????

    All I changed was the box, bled it out & everything before putting it to use etc.....

    Checked the gear mesh & their doesn't seem to be any binding there at all


    Would the YJ box have a much smaller piston then the ZJ box which is smaller then that Grand Waggy box??????
    I'd really like the grand to steer effortlessly on the road like my old late 70's early 80's Chevy truck's did

    Anyone have a link or resource to saginaw steering box specs?

    I did some research on NAPA's website today & according to their website YJ's and 80's J10's, Grandwagoneers, and J20's all use the same part# box (which is what I have on my Grand currently)


    My problem must be due to them selling the same box to cover so many varying vehicles, so I have two options go back to the 3 bolt ZJ box (which should work fine with my Kevins steering brace)

    Or mod the pump to help the current box work as easily as the previous ZJ box (which doesn't make much sense since the ZJ box is supposed to have a 12.7:1 quicker gear ratio compared to the YJ's 14:1 gear ratio-the damn YJ box should be slower but WAY stronger)

    When I say easily though I'm refering to the "turn in effort" (http://www.pirate4x4.com/forum/showt...aginaw+effort), perhaps there is an issue with the "T-bar" in my new box being so much stronger for use in short AND long wheelbase rigs compared to the original ZJ box's "luxury" design (and hopefully its replacement)

    Added a final update. The PSC box has been replaced with a Waggy box and the PSC is now a trail spare since that's about all its good for.

    dave, i would open up the PSC and find out what’s wrong with it – should be repairable – worst case you just clean it up and put it back together - it’s a damn shame you couldn’t get PSC to step up to the plate and back their product
