I was able to get the steering column reassembled this weekend, about 90% happy with it.
I took a few pictures and will describe some of the work, but this wont be a step by step guide. The steering column is not terribly tricky, and I only used one special tool (lock spring compressor) to do all this work, but I highly suggest you have a FSM in front of you, and patience. In regards to the FSM, I am using a 1982 (with 83 supplement) as reference. Only one minor difference I found with regards to the '81 steering column I am working on: the '81 sector shaft does not use a retaining clip, it is just a press fit. Even with the FSM, I had to look at some of the instructions for FS Jeeps to get all the relevant information. The FSM CJ section does not have too much info with regards to the column shift. Not the end of the world, is what it is.
Don't let this scare you, steering column work isn't too difficult, actually kind of fun, in a weird puzzle kind of way. IMO, the worst part was disassembling/reassembling the tilt lock prawl thingy's, not technically hard, just a PIA. Anyway, here we go:
This is as far as I tore the column down. I cleaned this part of the column with it in place. I had no need or desire to go deeper then this. If I would have removed the under hood steering shaft/shift linkage, I could have pulled this part out, but I had no reason to. This is the actual "joint" that allows for the tilt function. You will also see four screws. These are notorious for loosening,and these four didn't disappoint:
I used a 1/4" 12 point socket to remove these screws, what the FSM recommends, worked perfect. The internet/other sources say to use a 6mm socket, that would not work on these. Anyway, all four were loose. I pulled them out one at a time, cleaned them, applied red lock-tite, then reinstalled them. Quick picture, no thread lock from the factory:
Quick picture showing the FSM/grease I used. The FSM mentions using chassis grease, that will work, but I imagine the column would be stinking like wheel bearings. So, I used this stuff. Another benefit, it is plastic compatible. Some chassis grease will attack plastic, so be careful choosing a lubricant, as the column contains lots of plastic parts.
Part one of the "worst part". The two pictured "prongs" have stiff springs beneath them. So, you have to push them inward while simultaneously driving a cross pin through at a different direction. I worked one prong at a time, still a PIA.
Part two of the "worst part", installing the release arm. This arm is spring loaded with a small spring, which is easy to lose. Also, the previously installed prongs must be wedged open so that you can place the arm/small spring in place, hold it in position while you drive another cross pin in, all the while the spring loaded prongs want to snap back. Fun!!!!!!!!!
Next picture shows the sector shaft/gear/rack installed. These are the parts that move when you turn the key, which slides the remote rod for the ignition switch, and locks the steering wheel in place with the key removed. Not too tough, the stuff will really only go together one way.
Now, the FSM mentions installing the two sets of bearings in the above mentioned part before doing all the other work. I would not do this!!!! You have to press and pry and tap on the above column piece to get all the doo-dads in. With the bearings installed, the little balls could easily fall out. There are two bearings in the above component that support the upper steering shaft. I re-used the original bearings, they were fine. When I say bearing, I mean a plastic cage with 14 loose metal balls. Two of those. The balls are like BB's. They will fall out every chance they get if you are not careful!!!!!!!
I installed the inner bearing ONLY at this time, then installed the above column component. I used the tilt lever to make it easier slide this part on. Before this part goes on, the outer steering shaft has to be installed onto the inner steering shaft. I did not take a picture of this. There is a plastic block that connects the two shafts together and allows for the tilt function. I took this plastic piece out and reinstalled it. At first, I couldn't figure out how to get the plastic part out. Don't pry on it. After playing with it for a bit, you will figure it out. Wish I could be more helpful, but once you do it, you will see why its hard to explain how to do it. When you slide this component on to the shaft/column, be mindful of the bearing, easy to knock the little balls out, and be gentle when you slide the rack on to the remote rod. Took me three tries to get this together without some ball bearing falling out. I "think" replacement bearings are one piece deals, might be a worthwhile expenditure to preserve your sanity!!!!!
Once the above piece is slid on, get the two set of holes on each slide lined up and reinstall the pivot pins. You just tap them in with a hammer and punch. When the holes are lined up, the pins will drive in very easy. If you have to beat on them, you have a problem.
Next, I installed this lower spring/guide/retainer. Pretty easy. Not sure why you have to grease this part, but that's how they are/FSM says to do.
Next, I installed the column jacket. It slides right on, three screws hold it on. Since this is a factory column shift column, there is light bulb/grey wire that needs to be routed. The light is for the column mounted gear indicator.
