ASE A4 Steering Suspension Practice Test
1. A technician is using a steel hammer to remove a loose tie rod end from an aluminum steering knuckle. Which of the following is correct?
- A. Care should be taken not to strike the threaded ball socket.
- B. Care should be taken not to strike the loose tie rod end.
- C. Use a puller not a hammer to remove the tie rod end from the steering knuckle.
- D. Use a puller to apply pressure while striking the steering knuckle with moderate force to remove the loose tie rod end.
Answer A is wrong. Use a puller on aluminum parts. They also save threaded parts from unwanted damage.
Answer B is wrong. Striking an aluminum part with a hammer can easily dent it or cause irreversible damage.
Answer C is correct. Using the appropriate puller can save time and the part that’s being removed.
Answer D is wrong. Answer C is correct.
2. Technician A says Electric Power Steering systems require inputs from the steering torque sensor and the vehicle speed sensor to operate the system's electric motor. Technician B says to use a scan tool to retrieve trouble codes from an EPS system. Who is correct?
- A. Technician A
- B. Technician B
- C. Both A and B
- D. Neither A or B
Answer A is wrong. Both technicians are correct. These systems require inputs from torque, angle, and speed sensors.
Answer B is wrong. Use the appropriate scan tool to retrieve trouble codes and view system data.
Answer C is correct. Both technicians are correct.
Answer D is wrong. Read more about EPS power steering systems in the read more section.
3. There is a growling sound coming from the front of a vehicle that increases with vehicle speed and gets louder while turning left. Which of the following is causing this noise?
- A. A cupped left front tire tread.
- B. A cupped right front tire tread.
- C. A bad left front wheel bearing.
- D. A bad right front wheel bearing.
Answer A is wrong. A cupped tire changes its pitch from one surface to another. This change in pitch is true with all tires, but much more pronounced with a cupped or scalloped tire.
Answer B is wrong. A cupped tire will make a humming or growling noise.
Answer C is wrong. The weight of the vehicle works the bearing on the outside of the turn. For instance, a faulty left front wheel bearing is loudest while turning right.
Answer D is correct. A right front wheel bearing is loudest while turning left.
4. Which of the following is used to flush old dark colored power steering fluid from a hydraulic power steering system?
- A. Solvent
- B. Brake cleaner
- C. Carburetor cleaner
- D. Power steering fluid
Answer A is wrong. Flushing the system removes contaminants and debris.
Answer B is wrong. Brake cleaner is not used to flush power steering systems.
Answer C is wrong. Carburetor cleaner is not used to flush power steering systems.
Answer D is correct. Power steering fluid is used to flush power steering systems. Some manufacturer's recommend flushing with a solvent free power steering cleaner before a regular fluid exchange or every 50,000 miles.
5. Which of the following is true about directional tires?
- A. Directional tires tend to hydroplane more than standard all-season tires do.
- B. Directional tires must not be rotated front to rear.
- C. Directional tires must be dismounted and remounted if rotated front to rear.
- D. Directional tires are designed to spin or rotate in only one direction.
Answer A is wrong. Directional tires are designed to channel water away from the center of the tire and outwards, reducing the chance of hydroplaning on wet surfaces.
Answer B is wrong. The left front tire may only be rotated to the left rear. The same is true for the right front tire; it can only be rotated with the right rear. Directional tires have a V-shaped tread pattern.
Answer C is wrong. When mounting or rotating directional tires, make sure the arrow is pointing toward the front of the vehicle.
Answer D is correct. When rotating, never crisscross these tires. The tires must be dismounted and flipped before moving to the other side.
