    The ujoints in our steering shafts tend to develop play. You can try tightening the sector shaft/worm gear mesh very slightly, which may help some. A lot of play also develops in the spool valve area of saginaw boxes. If it's really bothering you, give Matt at West Texas Offroad a call and he will be able to explain what's going on a little better and let you know your options.

    I appreciate the feedback and suggestions from you guys. I will shoot off an email to Kelvin and get his ideas first since that is where the box was bought. Thanks again.

    Awsome write-up. I plan on putting a PSC in my WJ soon. I called them up and the pricing is pretty reasonable. Let us know what turns out to be with the slop you are experiencing.

    one problem with my box ive developed, is that some how the threads in one of the ears have become worn down and the bolt became loose and fell out, no idea how it happened or why but a longer bolt and an nut solved the problem pretty quick
    This person should be taken as seriously as a heart attack while piloting a zeppelin over a bacon factory, which is the most serious of heart attacks, because if that zeppelin crashes into that bacon factory all of us will be without bacon and that simply will not do.

    So after having this box in for a year and a half and doing a fair amount of wheeling with it, and less than 1,000 road miles, I think it's about done. There is a considerable amount of lateral movement in the sector shaft. I'm gonna contact PSC when I get back from Moab to see if there's anything that can be done, but I'm guessing I'll be needed another steering box.

    I swapped out my PSC box for a Waggy box, I couldn't justify spending another $400. Fixed my steering problems so far (fingers crossed).

    Dave, I sent in a concern back in April and this was their response. I have done nothing with it or to it yet though.

    Have you tried adjusting the box? Can you get me a casting # from below the
    four bolt Cover.

    Subject: Enquiry from PSC Motorsports


    About 10 months or so ago I bought a box for my 95 ZJ based on one of the forum reviews (Mallcrawlin) and had it professionally installed at JC Fab & Design. I believe the 621 is the unit I bought. Anyway, since that time I've put about 3,000 miles on it and it has developed quite a bit of play (slop). I've also upgraded the other steering components but apparently they are not the problem. I'm wondering if you have any ideas or suggestions.
    Thanks.

    It held up just fine out in Moab, but the amount of play in the sector shaft has definitely increased over the summer. I emailed PSC and am awaiting a response.

    I am working with Old Town Customs in Texas right now and they are the test bead for Tom and the guys at PSC, so if you need an in let me know I might be able to help out.

    Hoping to get Amsoil as the recommended fluid for all the PSC stuff. Carl at OTC is currently testing the tractor fluid on a full hydro buggy with rear steer to see if that cures all the overheating issues that are common with full hyrdo. The initial test last weekend turned out great, so we shall see.

    Negative. At this point it really doesn't matter either, it's well out of any warranty, but for the money spent it should last longer than it did.

    Something doesn't sound right with that box. I've had one on my Jeep since 2004 and I put one on my truck in 2005. Both working fine.

    So no one at PSC has answered the phone since October?? Or did you not call them?

    Haven't tried calling them, only email. But the product is out of warranty so I wouldn't expect them to do anything anyways.

    I wasn't referring to the warranty. I was wondering what they have to say about it wearing out so quickly and it having (I assume) not been abused. They claim high quality, yet there are two cases on here where their boxes have failed with little use. Just my .02

    What year waggy box do I want to buy? Can I buy it at a auto parts store or do I have to get it at the jeep dealership? Mike

    Ah!

    If I have a problem with something, I normally just call. It's a lot easier to get it fixed than farting around with emails all day.

    You sound like my boss, his desk is right next time mine and he will email me with shit to do.

    I have a 94 ZJ and the stock steering gear box is about to let go any time now. I looked at the PSC box as well but sounds like the Waggy box might be a good fit as well. Anyone know if there is a stock Waggy box that will bolt in and be able to add the 4th bolt? I need to pick one up very soon so I want to get it tight the first time around. KNow what year waggy box I need and any mods I need to do for the install. Thanks. Later...Clint

    You'll want a box from 1980 or newer with the o-ring fittings, that way your fluid lines will be a straight bolt on. Everything else like pitman arm (make sure you use the ZJ one) and steering shaft will already bolt up.
