What each one is, what adjusts it, and whether it makes the car pull or eat tires.
Top of the tire tilted out (+) or in (−). Too much wears one tire edge.
Steering axis tilted back (+) for stability & return. Doesn't wear tires.
Wheels point together (toe-in) or apart (toe-out). The #1 tire-wear angle.
The car pulls toward the side with more positive camber, and toward the side with less positive caster. Side-to-side difference (cross-camber / cross-caster) over about 0.5° shows up as a pull. Toe doesn't pull — it wears tires and cocks the steering wheel.
Turn the tie rods, cam bolts, and offset ball joints. Watch the angles, the wear, and which way it pulls.
Reason first, then reveal.
ASE-style. Pick an answer to see why.
