All angles, presets and handling indicators in this module are simplified teaching models—not vehicle specifications, adjustment targets or repair instructions. Verify exact ride-height, loading, alignment, tire, steering and suspension procedures from the assigned vehicle service information. Browser completion is not practical competency.
Start with the geometry language
12.1 establishes the reference angles and handling relationships used throughout suspension, steering, tires, alignment, NVH/handling diagnosis and ADAS-related chassis service. Next planned module: 12.2 · Suspension Designs, Springs & Dampers.
Learn the reference before judging the measurement
Camber, caster & toe relationships
Move the fictional alignment values and watch the views change. The indicators below are normalized teaching cues, not a prediction of how a real vehicle will pull, wear tires or handle.
Teaching convention: positive toe = toe-in, negative toe = toe-out. Real alignment machines may display units/sign conventions differently; follow the equipment and service information.
Inspect first. Measure second. Interpret together.
Ordered chassis reasoning sequence
Complete the sequence in order.

Concept knowledge is not alignment competency
Use approved alignment equipment, a training model or an appropriate vehicle under instructor supervision. Observe the learner identifying, measuring, interpreting and verifying the assigned geometry. Do not infer hands-on alignment skill from the browser score.
