500

· Improper ride height most directly affects this alignment reading.

  1. What is camber?
500

· (DAILY DOUBLE) Loss of EPS assist while driving still allows steering because of this connection.

(DAILY DOUBLE) What is the mechanical steering linkage?

500

· A bent steering knuckle will most likely affect this angle.

  1. What is camber?
500

· Failure to road-test can miss this complaint.

  1. What is noise, vibration, or pull?
500

· Steering effort differences side-to-side are often caused by this condition.

  1. What is cross‑caster or tire pull?
