Lots of ideas her but nothing very local to you. Minneapolis is a days drive or around 450 miles. Then you will be stuck there until you get the coach back together.
So here is what I would do if you feel up to it and have a place to work in this weather.
Call Dave Lenzi and make sure he has time to rebuild your knuckles. Remove both front knuckles and cart them down to Pembina (70 or 80 miles) and ship them FED-EX ground to Dave. Get a receipt from Canadian Customs on your way south so they can not later say you are importing something on the way back. Have the knuckle return shipped to the same Pembina location and held for pick up. Get Dave to include a receipt that says "repaired antique auto part using customer supplied core." Take pictures of them before shipment to keep the Canadian Customs people happy upon return.
Removal of the knuckles is not difficult:
Loosen big nuts in middle of wheel
Jack up and remove wheels
remove brake calipers
remove shocks
disconnect tie rod
disconnect upper and lower ball joint
remove knuckle and place in shipping container
That is from memory. I hope I remembered everything.
Installation is the reverse of the above.
I know of no adjustments required other than torquing the big nut in the center of the wheel.
When I sent my knuckles in to Dave by FedEx ground, they delivered and returned them in one day each way. (It might take 2 days from Penbina). I had them back in 6 days total.
I seriously doubt replacing the bearings will improve your steering any, but if they need to be done for other reasons, then by all means do it.

Brian,
There is no way of knowing whether the bearings, hubs, knuckles are good or bad unless they are disassembled, cleaned, and
inspected.
CV joints are another story which I'm not going into.

good advice and logistics...only problem is...how do I know they should be done other than I have no hx...they seem tight
but....should I change them ...I guess I have been thinking a person familiar with good and bad as it applies to gmc front bearing
and cv joints would know upon examination if they were good and do not need replacement or if iffy...I got new front Timkins from
jim K to have on the road in case of trouble...neither happened for multi years...Brian 77 ele 455

Lot of people rent the bearing tool and have the shop forman call me so I
can guide them on the front. Majority of the time the knuckles will need to
be replaced as they will be loose fit.
You can get the rebuilt one from Dave Lezi or us as we size them to last.
As Jim Hupy mentioned, check the rear for play in the arm.
The rear is a snap to grease. Yes if you have the time , do it properly or
just grease it .
I have observed Penski lub their fleet, they never lift it at all.
Better to have ome rease than to run dry till you have time to do it right.

I can tell you that both Dave and I can tell you that going to one ton has
its issues.
Since Dave and I know how to make the origional system work for 80-100,000
miles , your not doing justic.
People like Bob Duahugh and others can explain the short comings of One
ton, we do sell one ton, so figur that one out.

Jack the coach up and pull the knuckles put them in a crate drive to the coming west ups place in the UPSand
ship them to JimB or JImK and it will probably cost you less than driving to the class West I lace

DO NOT remove the shocks without unloading the torsion bars first! Or jack under the control arm to stop it from traveling downward due to spring pressure. A little bit dangerous but doable safely with the right technique. You do not need to remove the shocks to remove the knuckles anyway.

You are right. I was thinking about removing the lower control arms or torsion bar. It is Not necessary on knuckle. It has been a long time since I did one. Front coach weight does need to be supported on the lower control arm. Do not let the lower control arm just hang down. I usually jack it up in the center and then put some jack stands or 4x4 cribbing under each control arm. Then drop the coach on them. I leave the lowered jack in the middle with a light amount of weight on it just for some extra safety.

Brian,
There is no way of knowing whether the bearings, hubs, knuckles are good or bad unless they are disassembled, cleaned, and
inspected.
CV joints are another story which I'm not going into.

Yes the zerk fitting hole can be drilled in place but the axle and bearing has to be out. Jim Kanomata has a jig available that works great. You just need a 6” long 1/8” drill bit. You also have to cut grooves in the bearing spacer with a Dremel tool.
Then tap threads into the outside hole and thread in a grease fitting.
The only problem with this is that you must first determine whether there us wear on the hub or inside if the knuckle.
You can do this with calipers but an expert like Dave Lenzi and others will do it properly which is why the recommendation to ship them off for rebuilding.

That is exactly why I sent mine to Dave Lenzi. I did not want to accumulate the tools required, and try to do it correctly the first time try while also trying to learn a new skill that I hope never to need again.

Brian,
I know we have talked before. My daughter and her husband live in Boissevain.
I was unable to connect with you last summer due to time restraints.
If you decide to remove the knuckle assemblies, they can be shipped thru a broker in Dunseith, ND just over the border.
My daughter uses them all the time for her package deliveries.
If you are interested I can get you that information.

Bob, you have to be pretty sensitive to feel the change in camber during
jounce resulting from the slightly taller knuckle. I seriously doubt many
could feel it—I used to race cars and everything I feel is an improvement.
And I’m trying to think what damage it does. A bit more negative camber on
the outer wheel during body roll is actually a good thing, it seems to me.
It will reduce roll understeer slightly.
When I did my front bearings, I replaced the bearing on one side and had to
replace the knuckle on the other side. After removing the halfshaft and
caliber, the hub fell in my lap. The bearing had spun and the race was
loose in the groove it had worn. I had no idea there was a fault, and the
coach didn’t drive any differently after replacing the knuckle. Those
bearings had been serviced only 25k miles previously, by the PO.
One thing I can feel with distinction—better front brakes. And my old
brakes were fine, with good calipers, hoses, pads, and rotors. That extra
diameter makes a real difference.
The adjustment of the stock bearing depends on having the correct spacer,
and the prescribed spacer being correct depends on the holes in the knuckle
being perfect. That means that replacing a bearing just about necessitates
replacing the knuckle for those who don’t have the skills and tools to
measure not only the diameter but also the roundness of the hole. I have T
gauges and good micrometers and I fiddled with it for a hour to be sure.
Ken Thoma used a special three-point hole micrometer and it took him about
five seconds. But a loose bearing will spin and a tight bearing will
destroy itself.
I did not drill my knuckles. Dave didn’t provide the one I bought from him
with a zerk, and I didn’t have a jig.
Greasing the bearing still requires loosening the drive axle and backing it
out so you can see grease emerging past the face seal.
All freshly rebuilt stuff from Dave is great, but not cheap. And Dave is
not exactly sitting around wondering how he’ll fill his time.
And for those of us with ‘73 coaches, there is also the issue of
unreinforced lower control arms that can fatigue.
The one-ton kit doesn’t provide a better bearing, but it does provide a
more serviceable bearing. And a failing bearing won’t take the knuckle with
it, requiring that both be replaced. Replacing the bearing doesn’t require
popping ball joints, and it doesn’t require special tools. The bearing is
also more available.
For a front end that’s tip-top but for bearings, sending the knuckles to
Dave is a good approach. But if one needs to reinforce the lower control
arms, and replace the bushings, the one-ton kit will be cheaper. And the
bonus is 12” brakes on the front, in return for a geometry imperfection
that nearly everyone does not notice.
By the way, I have one-finger steering on my coach with
loose-as-wobbly-shopping-cart caster-wheels on the back. The big difference
for me was new bushings on the front, new gear box, and a better alignment.

Brian:
Your statement "taken off and tried and tried different positions on that blue telescoping shaft and everything is tight and no change" makes me question whether you aligned the steering column and box correctly. Someone, Rob maybe, wrote up the detailed way to do it. Do that step by step if you haven't.
