PSC Motorsports 621MR Steering Box

[BigDaveZJ]

Eh, it was out of warranty anyways, so I can't blame PSC too much for not covering it. But under the rather light use it saw it should've lasted longer. In another PSC thread somewhere I read that PSC even admitted they don't have the proper equipment for QA to make sure this kind of stuff happens. If I paid retail for the box and had this happen I'd be pretty pissed, but oh well. Now I've got a blingin paperweight!

i emailed kelvin a link to this thread - his email reply to me:

I read through the post. If Dave would send the box back to us I would find out what the problem is and get it fixed and 90% of the time no matter how old it is all you have to do is pay freight to us. Every Gear is tested and road simulated. I asked for the Casting # off of the Box for this reason, the #26055055 Durango box which everybody searches for is not all it is cracked up to be. There is no sector shaft support like the earlier #962 castings that we use. It is however a large piston which in a stock sized tire vehicle works fine but put it in a large tire locked situation and the sector shaft will walk in the housing. We did use the #055 casting for a short period of time until we saw this issue rear its ugly head. Now the #055 gears, if one comes across our path, is gutted and the housing hits the scrap pile. Anytime a customer calls with a problem with one of our gears and they are found to have the coveted Durango box I have them send it in and I replace it. Thanks for the heads up Ron. Please feel free to post this on the site and have anybody with any problem with our product call. We don’t bite like the competition.

dave, i say give him a shot at fixin' this thing

[BigDaveZJ]

I've tried contacting them twice already with no response, not really sure it's worth it at this point. Best case scenario now I guess is if they do end up fixing the box I can put it in Pam's ZJ and keep her stock box as a spare since with the high # of ZJ's I wheel with the chances of a box breaking are pretty high.

Wow GREAT info about the DUNGrango box... All along my gut told me that it sucked.. After all, how is a THREE bolt box even close to an upgrade?

[fpkites]

I did some research on Napa's site, and it looks like the current waggy box part number is NSP 88277079 (Reman)

Figured that would help folks that are checking for parts store replacements.

Thought I would bump this. This winter I had my box replaced (due to cold/wet, not a drivway thing I would do). Anyway they replaced it with a AC Delco ZJ unit. Upon replacement the turning was more difficult at near-zero speed. I have Kevins support. It was never that difficult before the support (with a worn steering box). I am begining to wonder if the stock mounting actually flexes a bit, and any additional support forces the steering to take the full stress. At least that theory fits all the comments to date. I plan on looking into the pressure mod where I read about drilling out a couple holes internally to increase flow.

[DJJordache]

could just be a bad reman job, I had that happen on my brothers XJ (same box as our ZJ's) so I went and got ANOTHER reman and that one was fine.

[BigDaveZJ]

So my Waggy box has now fully shat itself as well. Significant lateral play in the sector shaft, AND my pitman arm is cracked. Now to find a receipt for the box from 7 years ago, lifetime warranty!

3+ years, not quite the oldest thread revival. Good job but better luck next time...

[Ted_Z]

Epic old thread revival...

only because I likely have a steering gear swap in the near future. I'm currently on my second box, 3-bolt, with a brace. Currently getting some strange noises from the box, and some sector shaft play. Looking to go to a 4-bolt waggy/J-10 box. Do the 4-bolt now, and add hydro assist this winter. PN I'm looking at is LARES 1182.

Edited to add, Actually looking at ACDelco 36G0052 now. Application is for:
JEEP CHEROKEE 1980-1983
JEEP GRAND WAGONEER 1984-1991
JEEP J10 1980-1988
JEEP J20 1980-1988
JEEP WAGONEER 1980-1983
JEEP WRANGLER 1987-1995

Well, it seems I cannot find any supplier that has a post 1980 wagoneer or J truck steering box available.

Does anyone know an alternate 4-bolt box with o-ring fittings that would work? I read that the Durango box would be an "upgrade" but only has 3 bolts.

[BigDaveZJ]

I've gotten my 4 bolt boxes from Napa, let me see if I can find a PN.

hmmm, says "delayed"...

I found a used one, $100 shipped. I can get a rebuild kit for ~$20 and I'll be tearing it down anyway to tap for hydro assist anyway.

Drop ships from the rebuilder, not one of their warehouses.
