I don't know the answer to some of your questions, but I owned a 1976 Chinook with old, worn-out shocks. Was finally able to replace with all custom...and it made a HUGE difference. Wish I had been able to do it earlier. I don't remember the cost, but around $500??? The front coil springs were ordered by a great Toyota mechanic so not sure where they came from. The rear were a private business in Grand Junction, Co. Don't know if they are still in business. Hope this helps a little.

You might try Douglas Automotive in Tucson (just off I-10 near Marana). They worked on my 76 Chinook, and I was very pleased.

What year and engine?

Not familiar with the 22R, but it sounds like it could be the starter. Just an idea of what to check.

Ok...let me explain a bit. I have a 76 Chinook and landed a 77 pickup for parts. When I had to have my engine rebuilt, I used the 77 so I could continue to drive my truck. That transmission went into my truck, so I was left with the original trans from my Chinook. This was in 2011 and that tranny has been in my storage since. It was in good condition. Don't even remember it leaking... So...I am planning a trip up there (Utah) about mid-May. Not sure how to go about shipping?? but maybe you would have an idea? I'm not interested in much money for it. Something to cover my trouble and shipping costs?

I actually have one. It's from a 1976, but I have found that the parts are nearly all interchangeable. The one now in my Chinook is from a '77. It is in Utah, and I am currently in AZ, but maybe we can work something out - if you're not in a big hurry.

I can't address many of your questions, but I have a 1976 Chinook. Think it is probably smaller than yours. Anyway, I put custom springs on both front and back. Both to raise it a bit, but mostly to help with the instability. It came with little 14" tires. Couldn't do anything about the front ones, but put bit 15" on the rear...and boy...did that help with the stability issue. I think the thing you are describing that the steering column goes into may be the steering box? Good luck. Hope this helps a little.

30 x 9.5 x 15 They make it so much more stable than the little narrow 14's.

I don't know about the gears, but I have a 1976 Chinook. Also from Colorado - although I'm mostly in AZ now. But...with a 20R it is definitely a challenge with the hills (mts). Mine is so old that I have to re-adjust the timing and idle each season when I go to high altitude. Don't know if you do that on yours, but it REALLY helps. I also put big, god-awful 15" tires on the rear, which helped with the stability tremendously! Wish I could have done the front to, but not enough room. Good luck and enjoy!

Sorry it took so long...been out of town. I tried that, but without any luck. Have already tried replacing most, if not all, vacuum hoses. Will have to try something else.

You probably need a new rear end. This happened to me last fall with my 76 Chinook, and had to replace the whole thing. Good luck.

Sorry, don't think I can help. I've got a 20R, but couldn't identify it either:(

I have a 1976 Chinook with a 20R engine. It has decided to not idle. Usually. Once in a while it will just fine, but mostly not. Especially when I have been at speed and then stop. Like in city traffic. I have done the carb kit. Checked wires, plugs, ignition coil. Everything I can think of, but nothing seems to work. Anyone have any ideas?

I don't know about the rig you have, but I have a 1976 Chinook which came with 14" tires. Really not good enough. I finally was able to put 15" wider tires on the rear. New rims, of course. But what a difference! Wish I could have done it years sooner.

Hi! Glad to find you. I have a 1976 Chinook - which just lost a rear wheel and part of the axle:( In the shop and looking for a replacement. Is the rear end on the Chinook heavier than what was on the same-year pickup?
