Question 1 · A4 Suspension & Steering

What is caster?

  1. The ride height
  2. The tires' toe-in
  3. The forward or rearward tilt of the steering axis viewed from the side
  4. The inward or outward tilt of the tire viewed from the front of the vehicle
Show the answer

C. The forward or rearward tilt of the steering axis viewed from the side — Positive caster improves straight-line stability and return.

Question 2 · A4 Suspension & Steering

What is toe?

  1. The difference in distance between the front and rear of a pair of tires
  2. The rear axle's thrust direction compared with the vehicle's centerline
  3. The tilt of the tire from vertical
  4. The tilt of the steering axis
Show the answer

A. The difference in distance between the front and rear of a pair of tires — Incorrect toe is the biggest cause of alignment-related tire wear.

Question 3 · A4 Suspension & Steering

A vehicle pulls toward the side with less positive caster. What does this mean for a vehicle with more caster on the right?

  1. It doesn't pull
  2. It pulls to the left
  3. It pulls to the right
  4. It pulls only when braking
Show the answer

B. It pulls to the left — Caster pull is toward the side with less positive caster.

Question 4 · A4 Suspension & Steering

Which tire wear pattern is typical of excessive toe?

  1. Cupping in spots
  2. Feathered edges across the tread
  3. Wear in the center only
  4. Wear on both outer edges only, from underinflation
Show the answer

B. Feathered edges across the tread — Feel the tread across: sharp edges on one side point to toe.

Question 5 · A4 Suspension & Steering

In what order are alignment angles usually adjusted?

  1. Caster, then camber, then toe
  2. Toe, then camber, then caster
  3. Any order
  4. Camber, then toe, then caster
Show the answer

A. Caster, then camber, then toe — Toe is last because caster and camber adjustments change it.
