I have a 1993 f150. Problem is that the steering wheel can wobble back and forth about a half inch or so. I took the wheel off and it looks like there is a lock ring holding everything in place. I just wondered if there was a solution to this to fix it

 

Sounds like you need to replace the upper shaft bearings.

 

Do you know where I could get the bearings?
