Denny, I would have said you were wrong untill I saw that video. Very Nice!
I changed to 4° shims after replaceing king pins, front springs, shackles, bushings, shocks, tires, tie rod and drag link, and adjusting the steering box. I was still not happy with it, but the 4° shims did help.
Last week I replaced the steering box with an extra I rebuilt and, as it turns out, that was the problem.
After watching your video, I'm thinking about changing to 2° or 3° shims.
