Thanks again Bob C. Can someone educate me on the meaning of camber plus side inclination? I thought that side inclination was the angle of the kingpin; an inward tilt toward the top so that a line drawn through the kingpin would hit the road where the center point of the tire hits the road. Camber is the tilt of the wheel/tire from vertical. Positive camber means the top of the tire leans outward. So is camber plus side inclination the angle between the line through the kingpin and a line through the tire/wheel? It seems to me that this is a function of the angle of the spindle on the steering knuckle, which I do not believe can be altered at all? Am I right?
I measured the caster and camber using a gauge I have, and I got 4 and 5 degrees caster, left vs. right. I got 1/2 and 0 degree camber left vs. right. Both caster measurements are within the specs, and the camber on the left side (which is the side that is wearing faster) is within specs, but the camber on the right is just a 1?4 degree out of spec.
I'm not sure I understand the specs for toe out on turn. I read it that at a 15 degree turn the toe out is 17, but 17 what? And at a 20 degree turn, it's 23 3/4, but again,
what is the unit of measure? Is it inches, meaning the inside tire turns out 17 inches more than the outside tire turns in?
