I recently downloaded a document titled "GMC Motorhome Maintenance & Information Notes" dated February, 1993. In that collection of notes was the following bolded comment:
3A) Steering
Steering 17.5:1 ratio 2.95 turns lock to lock
A} Miscellaneous Steering
a) Center steering wheel: adjust, tie rods equally on opposite directions. b) Steering centering device: SAFE-T-PLUS $325 -
United Safety Apparatus Inc, 2150 Moreland Avenue S.E.,
Atlanta GA 30315. 800-872-7233 404-66~,1341
c) Telescoping steering wheel: Use column from;'68 to 76 Buick/Olds/Cad. reprint of procedure $3 from editor
Use from 74 to 78 full size GM cars
d) U shaped steering wheel: From 85/86 Olds Cutlass Supreme will fit and allow a better
view of dash.
The author, John N. Engebretsen PE, appears to have passed away. Is anyone familiar with the author's comment of "Reprint of procedure $3 from editor"? I am certain it's not too involved but perhaps some of the wiring is different. I have a 1972 Olds 98 Tilt/Tele I would like to swap in.
Thanks for any help.

Sir: you can not simply swap in the column as the lower half is motorhome only, but you can marry the two, or 3, or 4. The early telescopic feature should be 3" telescopic and later ones are only 2". You can also add features from the 1988 and up columns and to pre airbag. Like dimmer on the stalk, later stepper motor cruise switch, flash to pass, cornering lights and of course telescopic. The steering wheel is tricky with telescopic cause you have to have an unlocking lever. Some steering wheels can be modified to use Caddy type lever or a Corvette or KW type horn button unlock feature. Also you have to have a steering wheel with the correct length column cover on it to cover the 2 or 3 inched telescoped. If you do the dimmer on the stalk you will need to make the dimmer rod longer or get a donor column from a G10 that is correct length. It does make a nice touch to the GMC. I'll add some links to try and help.

Well it seems that both mr Stowers and Mr Sharpe did not include pics of the Telescopic feature. Seems I didn't take pics of the ones I've built. The upper column is different and you will need a different lock ring compressor tool for telescopic feature. When you change upper shaft at the knuckle joint be sure and keep index mark in the same place. There are pictures and take down instructions in all Cadillac manuals.

No sir I don't know anyone. It isn't really hard. I figure if I can do it, anybody can. It does get easier after you do 25 or so..

Do you know of someone out here in CA that has done an upper steering wheel tilt/tele swap that I can contact? This motorhome is new territory to me even though I have worked on many GM vehicles in the past like my '67 Toronado.

Great links below to the step by step swap"s thanks for posting - What part of the total column is motor-home only? Can these replacement columns be used all the way to the 'Lower shaft joint assembly'? (#8 on page 16-6 of the parts book) I guess another way to ask it: Is the lower vertical part that hooks into the steering gear box the only motor home "only" section?

Sir, the GMC column is 3" longer and does not have a plate that bolts to floor for mounting, and has a splined shaft. You will need the internal shaft and the housing including shifting mechanism. I have modified the later 2 piece shifter lever housing to work. When you swap the lower bearing/ tilt housing to get the eyelet to hold the dimmer rod do not forget to swap the transmission shifter detent block so your shifter will match the 425 3 speed and not the 4 sp od transmission.

Thanks for the comments Mr Boyd - My column has the broken pot metal, tilt flop's around and I also have to search for the gears. It's a mess. You don't happen to take on jobs like this do you???? I can do just about anything but this one scares me :-/

Sir, have you opened it up to see if it is the housing broke? Some times the 4 bolts that hold lower housing in place are loose and cause the flopping. You can get to these bolts by removing the upper tilt half and removing one at a time and using locktite tighten back up. If it is the housing broke send me some pics, I probably have an OEM one I could send you. It would be a good time to upgrade to later dimmer on the stalk style but you will need a donor column or 2 depending on how many features you want to add.

Mr Boyd, THANKS for the help!! If I pulled the whole works in tact - do you take on rebuilds? I'm 70 miles south of Chicago - not that long of a haul for me to bring it down/

I have the cornering lights on my coach, they are wired to the control column but they are not working. Do you have any info on where they are supposed to connect? The PO was unable to explain a lot of things to me due to medical issues. I think the column may have been swapped at the time the cornering lights were installed but I am not sure if that is the case. Sorry for the thread derailment but this is the first mention I have seen of the cornering light provisions in the column. Thanks for sharing your experience with the community!

If the cornering lights are made in the turn signal switch there will be 13 wires in the plug instead of 10. The last 3 wires is the switch not used. You can use a VOM to find which one is where you put 12v fused wire (from a bad memory brown) and the other 2 are right and left. The cornering lights themselves need to be grounded. If your column also has the flash to pass feature it has to have an extra 12v circuit added and can be tapped into for cornering lights.
