Alignment

Last reviewed: 2026-05-20

The adjustment and measurement of wheel and axle angles, including toe, camber, caster, thrust angle, and axle tracking where applicable. Correct alignment lets the tire roll in the direction of travel instead of being dragged sideways. It affects tread wear, handling, fuel economy, and how quickly irregular patterns return after rotation.

Check alignment after a significant road impact, suspension repair, steering component replacement, frame or axle work, or when irregular wear appears at the same position on multiple consecutive tires. Ask for before-and-after readings, not only a note that the vehicle was aligned.

Real-World Use

A maintenance manager reviewing tire wear records finds a steer axle consistently producing feathering wear. The truck is sent for alignment, and the report shows toe out of specification on one side plus a worn linkage note that must be corrected before the alignment will hold.
