The tech told me that he sees these boxes all the time. He said there are basically 2 types of P30 boxes when it comes to the stops, some have them, some don't.
Mine doesn't but they actually had a few that were the same as mine on the shelf.
Remind me again what is so special about this box and was this box used on ANY other vehicle?

Jared,
Was that a technician at RedHead? If so, I'm surprised, because I'm sure
they realize that ours is NOT a P-30 box. When I took my GMC box there
last year, they wouldn't consider any box but my own because they said ONLY
it had the correct stops.
It is very possible, of course, that your box has been replaced with a
non-OEM box. Some supposedly knowledgeable GMCers will even recommend a
rebuilt pickup box from NAPA. :-(

Thanks for that, I went through Bobs guide before pulling the box and pretty much stopped at key 7.
The input shaft on the box would rotate almost a 1/4 turn before the pitman arm began to move. There is a fuzz bit of slop in the blue joint, but it only translates to about 1/2 inch of play in the steering wheel and I will deal with that later.
I noticed it of course on my drive home with the coach but I was largely fueled by adrenaline as it had not gone down the road in 12 years and I only had 35 miles to drive.
I guess what I am asking is why didn't I just exchange my box for one that Red-Head already had on the shelf? I would have had it back in and bled by now. They had boxes that were identical inside and out.

Sorry, missed your post.
Yes the tech at Red-Head told me that.
He said what is inside of my box is typical to what an early P30 box should be. He also stated that back in the day GM didn't use stops in the P30 gearbox, not until the early 80's did the stops show up.
These are the standard Saginaw gearbox that has been used on dozens of different models of vehicle. Cars and trucks.
That does make more sense to me.... Why would GM decide to design a "Special" box for our coaches. You make more money using "off the shelf parts"
Right?
Jared
I need more input on this subject. I was told from the beginning of my steering ordeal "do not core out or get rid of your OEM steering box".....
What gives?

Yeah, I'm curious now myself. The Don Wirth paper appears to say that any 1/2 ton GM box from the 60's to 80's will work:
"When these same boxes are
used in the 1/2 Ton truck and our GMC a spacer is inserted
at the top of the stroke and the bottom aluminum pug has a
extended boss. These two items restrict the movement to
3-1/3 turns lock to lock as in our GMC's."

I thought I'd mentioned before, and I'm sure Don Wirth's paper covered, the
fact that the GMC MH unique Saginaw box has stops which are tailored for
its steering geometry. That's hardly a big change to a "normal production"
box. Especially when it limits the turning radius to the designed limit. My
fear, which is not universally shared, is that, without the prescribed stops
in the steering box, the turning radius limit will be imposed by the
steering knuckles hitting the A-arms, specifically, on the rivets/nuts
which retain the lower ball joints. With the hydraulic force available
from the power steering, and the mechanical advantage established by the
knuckles's steering arm and the small radius to those stops, a great deal
of force can be imposed on the lower ball joints and the supporting A-arm
-- a known weak point in the GMC's suspension.
Everyone's free to believe and use what they like. I hope their choices
are good ones and don't impose any risk to anyone. For my part, I'm glad
I've still got my OEM steering box with its correct internal stops and that
my knuckles do not hit the A-arms. That latter point is not coincidental.
When I acquired my current front clip, it had been completely rebuilt,
down to powder coating, by the PO. However, in his over-enthusiastic
renovation, he over-reinforced the lower A-arms and established
interference with the knuckles. I had to relieve that interference with a
die grinder. (For complete disclosure: Those knuckles and A-arms were
replaced when I installed the 1-ton.)

Ken, have you disassembled a Napa replacement box cross referenced with the GMCMH box part number and an original "from the factory" box to see what if any difference there is?
Am still confused by your previous post. edit..... what is different about the GMCMH box? What are the "stops"? Better question would be what controls the stops?
Apparently my box has no stops according to the tech at Red-Head.

Ken, I am not disagreeing with you, but Don's paper does seem to indicate that the GMC box and the 1/2 ton truck box are the same, right down to the 3.5 turns. I'm not saying they are as I have no first hand knowledge, but that does seem to be what it says.

I worked with those gears for years during the 70's and although there were a lot of basics that are shared on the 800 series gear, no 2 were really the same. Between input shaft size and configuration, spool valve settings, ratios, and stops, they were pretty vehicle specific. Over the years gears have been switched and bastardized by owners and service shops. If you know for sure that your gear is original, never let it get away. I would only trust 2 people to renew your GMC gear--Dave Lenzi and Ed Galubenski--both are retired GM technicians that live in the Flint Michigan area. The cost is over $400. From what I've read about the Red Head, I wouldn't be as comfortable as some appear to be.

Bob,
I agree!
I would like to direct everyone's attention to: Parts Book 78Z / Page 16-4 / Steering Gear / Key 18 - Kit, gear, pitman shaft.
In that kit starting with the pitman shaft and working outwards the first item you find is a SPRING; then a round plate, the
adjuster, and a sleeve.
When you turn the adjust you are increasing and decreasing the pressure on that SPRING which in turn pushes the gears on the pitman
shaft into Key 7 - Nut, piston, steering worm and rack.
I did a Google search for Saginaw steering BOX and came up with these pictures / line drawings:
https://www.google.com/search?q=saginaw+steering+gear&espv=2&tbm=isch&tbo=u&source=univ&sa=X&ei=lXPYU6OtJoeG8gGYj4Fg&ved=0 CC8QsAQ&bi
w=1137&bih=570&dpr=0.9#q=saginaw+steering+box&tbm=isch
I did a second search for Saginaw steering GEAR and came up with these pictures / line drawings
https://www.google.com/search?q=saginaw+steering+gear&tbm=isch&ei=wXPYU_K0OKKa8QGR4YGwAQ
I looked at many of the pictures / line drawings and I could not find one that has that SPRING!

I would like to preface this post with the statement that I am no expert on steering boxes. I am however familiar with steering systems, their components and replacement of them usually as the result of a collision. Other than trucks or SUVs on truck chassis most steering gears now are rack and pinion. Steering racks are durable and rarely injured in collisions even with substantial suspension impacts. Steering boxes however are more commonly injured when the front suspension is hit hard. Usually the sector shaft ( output shaft) will twist requiring replacement of the shaft. Repairing this requires either a specially trained mechanic/ a new steering box/ or a rebuilt steering box. Since there is not an abundance of qualified mechanics with quick access to the correct internal steering parts we are left with the second two choices. A new steering box for a late 90s Toyota 4wd truck is almost $2000 last time I needed one which was several years ago. I was able to purchase a reb
uilt oem steering box from Red Head for $ 350. This box went in the truck and aligned perfectly and has never been back. I've purchased several boxes from Red Head and none were defective. As far as I know, they are the only real local player in the steering box market. There is just not enough demand for this type of specialized work. If I need a steering box they are my only call other than a wrecking yard. A wrecking yard is not the ideal source for steering components since the rigs need to be wrecked to get there.
Ken H had me order a steering box ahead of his planned crash landing with the blown steering box seal. He had me order the chev p/up box that was mentioned here and was supposedly a comparable replacement. When he got here and we looked at the new box compared to existing they were different on one shaft ( input-output I can't remember ). Ken then loaded his box into his towd and went back to RedHead and they rebuilt his while he waited. At THAT point the tech could see exactly what box he was replacing and explained to Ken the differences. If you bring in a box they can match it or repair it for sure. But if you tell them what box to give you they will do just that. Never throw away a part until it has been successfully replaced. It is possible that an incorrect steering gear has been substituted in the past and the chev pickup box is a direct replacement for what you removed.

Jared,
No, I have not compared the boxes. In fact, I've only repaired a couple of
boxes -- and one of those not very successfully because the input shaft
seal blew after about 10,000 miles. My "knowledge" of steering boxes comes
only from Don Wirth's paper (written, at my request, in cooperation with
Bill Brown), discussions with Don, study of many other similar articles,
and the GMC manual.

David,
Re-reading Don's paper again (for probably the 20th time, but not within
the past few years) I must agree with your reading.
My position is thus not supported as I believed -- I'll have to hunt the
other sources that influenced it.
I'm still glad I've got the OEM box. :-)

Hi Rob
Apparently you did not find any reference to the presentation that Don Wirth did at the Spring 2005 GMCMI Convention at Ft. Meyers, FL on March 23, 2005.
I was in charge of the conventions at that time and I had invited Don to give a presentation on the Steering Box.
It is essentially the same as what he apparently did later for the GMCES.

Emery,
As you know, Don's health was already beginning to decline when he gave the
presentation at GMCMI Ft. Meyers. It wasn't long afterward that I, in
charge of GMC East's technical program, asked Don to do a write-up on that
material. As was our practice at that time, we offered him assistance with
preparation, editing, etc., and he accepted. Bill Brown volunteered to
work with Don and visited him at his home. The material in the paper is
Don's. The formatting and final preparation are Bill's. Hopefully it
covers everything Don presented at GMCMI.
I consider it a nice memorial to a great GMCer.

"" Steering racks are durable and rarely injured in collisions even with substantial suspension impacts. Steering boxes however are more commonly injured when the front suspension is hit hard.""
I totally disagree with that. Rack and pinion gears are very fragile and very susceptible to damage from curb bumps and potholes. Most are made with light weight materials . Most trucks have stayed with conventional gears although weight pressures are forcing many to go to rack and pinion on the light duty versions. Gears such as the cast iron SSG 800 like we have will not be damaged in frontal impacts.
