Steering column Question 67 C10

[Rockyrob]

Hi Guys Rob here from Australia, hope all are well, My 67 with column auto has an issue where the shifter rattles and shakes like crazy under mild acceleration , Seems connected fine at housing inside. I have a tilt column with i think a collapsible two piece shaft. There is a lot of play on the bearing at bottom end of top shaft which i think may be an issue, My question is , Can i remove the lower shaft only to gain access to replace the bearing by disconnecting at the rag plate on steering box or do i need to remove the column , Any suggestions most appreciated . And if i can do it where can i get the bearing/bush or whatever it needs. I have hopefully put some pics in this thread to show issue

Cheers
Rob
