ASE A4 Steering Suspension Practice Test

21. Two technicians are discussing a vehicle with independent suspension. Technician A says a faulty strut mount will make excessive noise when going over bumps in the road. Technician B says to replace the coil springs when replacing the front struts on a vehicle. Who is correct?

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

21.

Answer A is correct. A faulty strut mount makes a thumping or clunking noise when going over bumps in the road.

Answer B is wrong. Typically, when replacing struts, if the coil spring is good, it is reused, and the shock absorber/spring seat portion is replaced. A special tool is required to compress the spring.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Perform a bounce test on the vehicle to see if a shock absorber or strut requires replacement.

22. The right rear wheel of a vehicle 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 toe setting is 1.5 degrees positive (+) from specifications. 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. TOOT or Toe Out On Turns is an angle incorporated into the steering arm attached to the steering knuckle.

Answer D is correct. It's a non-adjustable angle built into the steering arms that creates a toe out while turning, keeping the tires from squealing. Check the TOOT angle if the vehicle's tires squeal while taking a turn.

24. Technician A says a vehicle with torsion bar suspension can be adjusted to repair ride height. Technician B says to take measurements before and after adjustments are performed. 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. They work like springs. As the vehicle hits bumps in the road, they twist and untwist to provide vehicle suspension.

Answer C is correct. Tightening the adjusting bolt turns a key that adds "twist" to the bar.

Answer D is wrong. Both technicians are correct.

25. Technician A says it is acceptable for a thin film of oil to appear on the shock absorber's shaft. Technician B says it's acceptable for a small drip of oil to appear seeping from the shock absorber's chamber. 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 thin oil film on a shock absorber's shaft is normal.

Answer B is wrong. A drip of oil from its chamber is unacceptable; this is a sign that it's leaking and needs replacement.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.
