73 Chevelle SS Intermediate shaft question

Post by marks454ss on Thu Jan 21, 2016 2:14 pm

Houston we have a problem. While reinstalling my steering column I pushed the pot joint cover toward the firewall onto the splines of the column. I now have a lot of movement up and down and side to side at the pot joint. I called Kevin (clanceman427) and he tells me his 73 is tight and I really didn't check it for looseness before removing it. Can somebody give me the measurement from the outside tip of the pot joint to the outside edge of the stationary half of the rag joint (the half that is part of the shaft)? I have about 19-3/4" collapsed sitting on the table with no looseness other than what is to be expected at the cross pin and about 20-1/2" installed in the car. I'm thinking the car was front end wrecked and the shaft has been collapsed and reused and the pin is coming out of the pot joint. I say this due to the fact that at 0 on the wheels the pot joint bolt was installed horizontal with the ground at 12 o'clock instead of vertical on the engine side of the shaft at 9 o'clock which I believe is the correct orientation of the bolt.

I'm assuming the gearbox would be the same distance either way

Mark what year did the colum com from for when I switched mine from a 73 I had to use my 77 Lower ( one with rag joint ) SO I am assuming since yours is a 73 you have to switch your lower arm from your original column to the new column you also have to switch the 73 plugs on the column from yours to the New one

I have my lower shaft removed and I just measured it. 18 3/16" from the end of lower rag joint flange (As you described) to the end of the shaft that goes in the pot joint. I currently have mine dis-assenbled. No pot joint on the end of the shaft. I think that the wire clip that holds the seal in holds the whole thing together tight. Is you'r clip fully seated? Maybe the "U" shaped spring clip inside the pot joint has become dislodged?

On another note be very careful with the seal. I tore mine last year and am having one hell of a time finding a replacement. I picked one up from the parts place and it is too small in diameter. The wire clip will not hold it in place. I am thinking of maybe cemeting it onto the top of the old seal. I cut the old boot off down to the round part that fits in the joint. I'm still trying to figure out something.

I have a previous post with some links.

The seal looks the same as what was used on '73-'87 CK trucks. LMC does not have one. They sell new complete shafts with u-joints.

I got up with Joe73 and his is out of the car as well. His measures 19 3/4 with the pot joint pushed all the way in same as mine. http://www.thirdgen. However when he started looking up part numbers for me in his GM parts manual there are different numbers for the shaft depending on whether you have a big or small block car same for the rag joint. I'm picking up my new gearbox from Napa tomorrow and will start from there and try to get this thing back together the way it's supposed to be. Wink

Thanks for the response!!  Yes, I bought that seal from them. I looks as if it would work other than the diameter. It is 2".  

Mine is 2 1/4". Retaining clip wont hold it and doesn't totally seal. 2 inch diameter is most likely previous gen.

Figured I would post some pics before I put it back on the car. I'm measuring 19 3/8" fully collapsed & 20 13/16" fully extended.(Can't take a pic and hold tape at same time) This was originally a small block car which is why my numbers differ? It has a BB now so I wonder why 2 different shafts unless it had something to do with exhaust manifold clearance. I have headers. The seal is from a jeep. There is no direct replacement seal for this that I can find. The seals that are available are 2" diameter. This is 2 1/4". This appears to be a non-serviceable item which is why I can't find any parts #'s, other than the shaft itself. This thing is nothing but a massive headache. Those of you doing any work on the shaft be careful of the seal!!!!!!!!!!!!
I do not know but I would guess '73 is the first year for the plastic injected shaft??
