it is the same as on anything else.1. jack up truck and get level2. position front suspension at half travel or ride height[sometimes the same, depending on truck and owner]3.with your steering wheel straight, you should be able to draw a straight line through your lower a-arm bushings through the inner tie rod or steering pivot through your upper a-arm bushing. this way everything is following the same arc. if it falls out of line, you have opposing arcs causing...bumpsteer. when the suspension travels the a-arms want to follow one path while the steering will want to follow a different path.4.with a straight edge, mock up where the upper mount would be. go from lower hole center through pivot center on steering rack to....new upper hole center! that will retain the correct geometry w/o bumpsteer. now remember that some camber is good, it is there for a reason. if you raise the arm too far, you will hardly have any camber change. while this sounds good on paper, it seriously affects handling, since the tire no longer cambers inward to put more tread on the road while turning. sorry that took so long. remember, measure once, cut twice. measure twice, cut once.
