1972 GMC Steering Shaft Slop. Cam/Bearing Gap

[gabej]

Hi
Regarding a 1972 GMC C1500 (Sierra Grande) Non-Tilt Column.

I'm getting 1/4" to 1/2" play in my steering wheel/shaft in an up down/side to side range. I'm also getting about 1/2" play in and out. It seems as if it is because the tapered bottom end my turn signal canceling cam isn't engaging with the upper steering column bearing. Reading posts in the forum the tapered end of the cam should take up the gap and shore everything up but in my case it's not. My hub when pressed into the shaft doesn't descend down the shaft far enough to take up the gap between the Hub and the cam therefore pushing it up-to the bearing. Is there an adjustment I'm missing?

Thanks for your help.
