<VV> Steering Wheel "Clunk"

Hi Bryan, Mike, and Paul;
After I sent out my question on VV, I went back and looked at the '66
manual and the Chevy Assembly Instructions again. I see what you mean
Bryan. Kind of a funny design though to have a .005" - .030" clearance
controlled by a spring? How do you have a variable clearance while under
constant spring tension?
I also remembered how hard it was to get the snap ring off the upper part
of the steering shaft and how much more difficult it was to get the snap
ring back on when I changed the switch. I had to pull up really hard on
the steering shaft while trying to push the snap ring down and into the
groove. This might have been due to the lower bearing spring pulling the
shaft away from me and the* tension issue Bryan is talking about.*
I do have some up and down play in the wheel, it doesn't seem excessive but
I need to measure it and see if I'm in the ballpark.
Looks like I'll be checking/adjusting the lower spring clearance to see if
that helps, Big job for a simple turn signal switch R&R.
Thanks very much Bryan, Mike, and Paul! Really appreciate the input.
