Well, I think I've got the source of my problem figured out. From what I can tell, the upper column bearing is binding up and moving around some inside the t/s switch. This makes the 2nd t/s switch I've put in this truck. The 1st one came from the Truck Shop and this new one is an AC-Delco brand that came from Classic Industries.
With that being said, does anyone have any ideas for keeping that upper bearing still and not moving around and binding? I've had the steering wheel off of this truck several times and haven't seen where I could tell that there are any parts missing inside the column. I did replace the t/s cancelling cam, thinking that maybe part of it's jobs is to apply some pressure to the upper bearing, but it did not help.
Any ideas are appreciated!
Thanks in advance!
