ASE A4 Steering Suspension Practice Test

21. A vehicle has a SLA suspension system. The coil spring is located between the frame and the lower control arm. Technician A says to place a jack under the lower control arm and raise the tire of the ground to unload the load-carrying ball joint. Technician B says to place the jack under the frame and raise the tire of the ground to unload the load-carrying ball joint. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

21.

Answer A is correct. If the coil spring is seated between the frame and the lower control arm, place the jack under the lower control arm. Raise the vehicle enough to move the tire up and down and in and out.

Answer B is wrong. Place the jack under the frame if the coil spring is seated between the frame and the upper control arm.

Answer C is wrong. Movement can be seen or measured with a dial gauge and compared to specifications.

Answer D is wrong. Technician A is correct.

22. A front-wheel-drive vehicle has four-wheel independent suspension. Its right rear wheel is 1.5 degrees toe-in from specifications. Technician A says to set the front toe on this vehicle before correcting the rear. Technician B says the right rear wheels toe setting is 1.5 degrees positive (+). Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

22.

Answer A is wrong. Inspect and correct rear camber and toe settings before setting the front toe.

Answer B is correct. Toe-in is positive (+) toe and toe-out is negative (-) toe. This rear wheel toe-in condition will cause tire wear and affect the vehicle's thrust angle.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

23. Which of the following is a non-adjustable alignment angle that should be checked after setting the front toe?

  • A. Camber
  • B. Caster
  • C. Rear toe
  • D. TOOT

23.

Answer A is wrong. The camber angle is adjustable.

Answer B is wrong. The caster angle is adjustable.

Answer C is wrong. The rear toe is adjustable.

Answer D is correct. TOOT or toe out on turns is an angle incorporated into the steering arms. It’s a non-adjustable angle that creates a toe out while turning that keeps the tires from squealing. If the vehicle’s tires squeal while taking a turn check the TOOT angle.

24. Technician A says a vehicle with torsion bar suspension can be adjusted to repair ride height. Technician B says on some vehicles, torsion bars are used in place of coil springs. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

24.

Answer A is wrong. Both technicians are correct.

Answer B is wrong. Both technicians are correct.

Answer C is correct. Tightening the adjusting bolt turns a key that adds "twist" to the bar. They work like springs, as the vehicle hits bumps in the road they twist and untwist to provide vehicle suspension.

Answer D is wrong. Both technicians are correct.

25. A vehicle feels bouncy and is oscillating at highway speeds. The vehicle's shock absorbers may be faulty. Technician A says it is acceptable for a slight film to appear on the shock absorber's shaft. Technician B says a small drip of oil appearing from the shock absorber's chamber is acceptable. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

25.

Answer A is correct. A slight film of oil on a shock absorbers shaft into the chamber is normal.

Answer B is wrong. A drip of oil coming from this chamber is not acceptable, it is leaking. The shock absorber must be replaced.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.
