Hi Bill, outside tire wear is indicative of too much "toe in" as was found at the shop. The truck can have left and right toe adjusted separately in relation to the center point of the steering gear, total toe is the left toe and right toe added together. It is possible for the total toe to be correct but not on center of the steering gear, this would result in one side being less toe than the other side and would easily show up in the steering wheel being cocked. The first thing they need to do is confirm the center point of the steering gear, then check caster, camber, and adjust the toe. If they are 100% sure of the center point, the steering wheel then can be re-clocked. Are all four tires and wheels the same diameter? are the springs in good shape or does the truck sit higher in the front or rear? If it is high in the rear, there will be too little caster IF everything else is stock. SAI is similar to the camber angle, in our case with solid front axles, it is the angle through the king pin as viewed from the front of the vehicle. The combination of king pin inclination and spindle angle will determine the camber on our trucks.
