Steering column question

[Jet Engine Mechanic]

Hello everyone. I've got a quick question.

I've got a '69 shortbed Chevy that I've been working on lately. I was in the middle of installing a new steering wheel when I noticed that the steering shaft inside the column can wiggle around. I can move it about an 1/8th of an inch in all directions. I was just wanting to know if any of you had the same problem with and what the fix would be. I was wondering if there is a bearing inside or something else that needs to be changed out. Thanks
