Don't intend to rehash a previous discussion that had a lot of capital letters but a timing mark was mentioned on the top of the steering shaft. Is that timing mark just a mark that looks like some one took a chisel and popped the end of the shaft to mark TDC or 12:00, I assume this is critical for the turn signal cancellation mechanism, also does the actual orientation of the u-joints on the lower shafts prove to be critical since it looks like there is about 6 positions the slider part of the shaft could bolted to the upper connector? Thanks for any comments.

Skip,
Yes, the column's only marked with a "chisel scar". And the relative
positions of all the rest of the components in the chain are critical.
Mark everything before you take it apart. And not with paint -- if you
clean things, you'll likely lose the marks.
One that hasn't been mentioned during recent discussions is the upper CV
joint, bolted together with the 6 cap screws, locked by bend-up tabs. To
clean and re-lube that CV requires that it be disassembled. BEFORE doing
that, BE SURE to mark the assembly so it can be reassembled in exactly the
same orientation of top shell to bottom shell. A Dremel tool with a
grinding wheel is my preferred method -- those shells are HARD. It's a
good idea to check for previous marks so old and new marks don't get
cross-matched. Without marking, it's VERY difficult to find the right
position -- those 6 quickly begin to seem like 36.

Ken,
I agree that you should mark all the parts when you disassemble the CV joint and lower steering slip shaft AFTER you make sure with
the wheels pointed straight ahead the steering box is on center. If it isn't the parts are assembled incorrectly and you're going to
put the parts back together incorrectly. ;-)

Skip,
Yes, that is all that mark is and mine wasn't even square (true -whatever).
As far as I could determine (we are going back a few years here in my case), the actual orientation of all the parts between the chisel mark in the steering shaft and the flat on the steering box input are not all that important. I do believe I tried all of them at least once......
I cleaned all the parts and used three different colors of china marker to keep track of all the different possibilities. It literally took me a day of trial assemblies to find a working setup.
There are four possible assemblies of the slip joint and six of the flange on the CV joint. But, the column end can be put on the CV joint flange more than one way. So check and try every thing. Make notes or you WILL get lost.
What I do remember is that only one assembly orientation of all I tried was actually correct.
A Word: DO NOT Assume that anything that can be disassembled has not been re-assembled wrong on the past.
Trust me on this one: It Is worth the effort!

Since I know it has been apart and probably not back together correctly, don't ask me how I know, would anyone know of a link
to a photo of a shaft out on a bench with all the parts lined up correctly. Just wishful thinking. Thanks.

yes...i took that apart cleaned and lubed...there is a way to do it without taking those cap screws off,,,,I can't remember how but I had the whole thing apart on the shop bench...I concluded at the time....last summer...that without the cap screws off,,,,nothing could be reassembled incorrectly,,,,and that I was also able to flush out and relube....felt smooth as silk....brian

matt...yes I took each component apart cleaned and lubed....I marked them first...then reassembled in every possible way...if each component is not assembled the correct way there will be probems assemblying other components as you work along....so after much time and consideration I believe that each and every component has one way of assemble that is correct,,,,and it just so happened that my marks on all components alligned the same as before....brian
