If people want better presentation, I know some of us will not do it as we
would be open to criticism .
Should be glad he takes time to do those things.
Jim B like rest of us do not work 8-5 5days a week and were not getting
rich either.

This topic has taken an interesting turn... If you want to see what's possible with vehicle-related video, check out Project Binky (Bad Obsession Motorsport) and Soup Classic Motoring; the first for the protagonists' skills, personalities and humor and the second for an interesting approach to video production. As Jim H points out, if it were easy everyone would do it. The best channels have Patreon subscribers at 2, 5, and 10 per video at the minimum. 1000 Patreon supporters at 5 bucks for a video each week is $20K per month. That makes it possible as a full time job - provided you have the personality and content dialed in. If Hal St Clair were so inclined, that project would be a winner.
I think weekly videos by a skilled and knowledgeable individual (not a company - whose motives would naturally differ) that took viewers through a single restoration would be compelling if done well. But the product is knowledge and entertainment, not service or parts sales.

Do I hear an "Amen!" ?
Having been "in the business" for nearly 50 years, all I can say (without writing a book) is anybody who hasn't done it has no idea what it takes to do it. Even the Duane Simmons Onan video I did at the Mariposa rally some years ago was a bear to do as it was a spur of the moment, hit and miss, hope-you-get-something-because-there-is-not-another-chance type of thing. And Duane had the vocabulary and presentation skills that made it relatively do-able. Don't ask about post-production. It's a miracle anything came of it at all.

I have some experience in doing tech video presentations for rallies. All I
can say is "It ain't as easy as it looks" I have shot, then reshot, and
sometimes reshot again to get a sequence that comes out the way it needs to
be.
I spent many years in a shop setting as a Vocational instructor trying
to make technical points about certain processes that I found easier to do
myself, rather than trying to explain it to the un-informed.
But, watching someone else do something technical is NOT THE SAME as
actually doing it with your own two hands.
Doing it in front of a video camera and facing concerns of proper
camera angles, focus, lighting, AND keeping the nomenclature specific and
exact is no easy task. Oh, yes I forgot about sound quality when you turn
away from the camera, too. Easier to wear a microphone that you have to
manage cords to. I have thousands of dollars worth of cameras, lighting,
monitors, patch cords, software mixing and editing programs just to do this.
"It ain't as easy as it looks, folks". Cut Jim Bounds a little slack,

I understand it takes some good time and effort to make presentations and videos. I was in business for 40 years and many times had to make presentations for Government bodies and corporate meetings.
If you are marketing yourself as an expert and a teacher, making a presentation to those who look up to you for your knowledge, shouldn't you clearly present correct information? Otherwise, what's the point of going to the effort in the first place?
Those who are trying to learn will take this information as gospel and end up with a coach that is a handful to steer.
If you know the correct information, is it Ok to just take it as just entertainment and say "good effort". Then just leave it out there.
Just my 2 cents.

I assisted Alex Ferrara at GMCMIs while he did his thing and am familiar with the centering procedure. Watching that video I found it more confusing than clarifying.
This is not attacking JimB, nor a comment on the presentation/video quality. Posting confusing information should be avoided.

Hopefully these videos will demonstrate that the subject is complex enough to dissuade the average owner from attempting to correct their steering issues and rather to find a qualified professional. Maybe that was the purpose, but how many of the viewers can find one within the distance they're willing to drive a coach - especially one with wonky steering?
Imagine how much time and effort it would take to make an instructional video that would truly allow and encourage a brave GMC owner to diagnose and even fix their own steering issues. But there's a real need for that, since the average front-end mechanic has proven that they can cause more problems than they solve when they attack the GMCMH.

If you want better presentation, don't bother looking at these and see if
you'll find better re. our coaches else where.
Think you all should appreciate what they are trying to do and accept it
for what it is.

So I'm fighting a back injury right now, and I'm not able to do much. But today I went out to the coach and checked the amount of turns lock to lock. It looks like about 3-1/4 turns. So, from Jim Hupy, this is not a factory steering box.
Am I screwed here? Does this box have the infamous "high spot" that corresponds with the input shaft flat aligned with the cover axis?
Or are all bets off?
It does require more hand movement than I would like to keep it straight going down the road. I have not yet removed the intermediate shaft to confirm the position of the input shaft flat, but since the steering wheel is out, I'm pretty sure that everything needs adjustment.

Greg,
Here's the best information you're likely to find about the GMC steering
box:
https://www.gmcmi.com/wp-content/uploads/2013/02/GMCMH-Steering-Box.pdf
From that, the GMC steering box is internally the same as the Saginaw box
used in most GM vehicles of the same generation EXCEPT that it has internal
stops to limit the travel of the pitman arm. Those stops are very
important because without them, the entire steering system can be severely
stressed. If you turn the steering wheel to its extreme travel then look
behind the wheel away from the turn direction, you'll find the ultimate
cause of that stress: The knuckle has on it a "stop" (a molded protruding
knob) which will be near or against a welded stop on the lower A-arm. With
the correct stops inside the steering box, those two should never touch.
Without those stops, that's the "steering lock". With the hydraulic force
available, there can be a LOT of force exerted on all of the steering
linkage. Probably the most severe is right there on the lower ball joint.
Measure the distance from the pivot of the ball joint to the end of the arm
on the knuckle. Now compare that to the distance from the stops to the
pivot of the ball joint. As a WAG, I'd say it's about 3 times as far from
the end of the arm (lever) as from the stop (fulcrum), so that the force on
the steering linkage (100+lbf?) becomes 300+lbf? on the ball joint. Not
good! You want those stops in the steering box!
HTH,
Ken H.

The GMC steering box has internal stops that prevent the knuckles from hitting the lower control arm. You should check that your box does that; if it doesn't it's best to change it. I believe most boxes have the center high spot - or whatever it's called. I don't know whether the stops can be installed later and you'd have to know where they are placed.

Before you start ripping everything apart, you can try one simple adjustment. No guarantees that it will make your steering problems go away, but in my case, it did help - however, Murphy's Law - I didn't try it or find out about it until AFTER I pulled everything apart and attempted to put everything right.
This is a tip from the GMCINFO site.
With the wheels set straight ahead, loosen and back off the locknut that holds the allen screw in place - this locknut is located on the side of the steering box. Back it off a couple of turns then back off the allen screw a few turns too.
Next, start tightening up the locknut. As you tighten it, it'll pull the allen screw along with it until the allen screw stops turning. Continue to tighten the lock nut until it's tight again. Take her for a spin and see if the handling is any better.
This procedure really improved the handling on my coach. A friend later thought my steering wasn't "tight" enough and tightened up the allen screw - I let him do it because he was an experienced mechanic. It did tighten up the steering, but the coach became impossible to steer over 20mph and even that required a lot of concentration - basically the coach was unusable. I re-adjusted the allen screw the way I just described and I've been driving the coach all summer like that. It still ain't rack and pinion precise by any means, but at least I can handle it without sweating bullets.

Ken : Thanks for that article. If that is the definitive guide for steering boxes, then I do have the right box! It is about 3-1/3 turns lock to lock. I will confirm that the knuckles do not contact the control arms. I feel much better about this, for now, anyway!

Here's a pretty good write-up of what the two steering box adjustments do....
http://www.tpub.com/basae/220.htm
Until I read that, I didn't understand that the steering box gear is designed with more lash when turning right or left vs straight ahead. Too tight, and the lash is taken out when steering right or left, making it harder to steer; too loose and the coach wanders when steering straight ahead.
When I thought a little more about it I realized that the lash when steering right or left is not an issue (if you have enough caster once you stop moving the steering wheel) since you are pushing against one side of the gear while steering towards or holding the curve of the road. If the steering is not centered, when you steer straight ahead you are really in the part of the gearing that has more lash - until you steer towards the center of the box when you reach the part that has less lash.
OK you experts! Did I get that right - or even close!?

Not an Expert, but you are correct.
