ASE A4 Steering Suspension Practice Test

21. Technician A says that loose power steering rack bushings result in vehicle wander. Technician B says worn rack bushings cause changes in toe. Who is correct?

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

21.

Answer A is wrong. Loose or worn rack bushings will result in vehicle steering wander.

Answer B is wrong. Loose or worn rack bushings will result in excessive rack movement. This movement can change the tie rod adjustment after hitting a bump. This is also known as bump steer.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

22. Two technicians are discussing the toe setting of a front wheel drive vehicle with four wheel independent suspension. The 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. There is noticeable wear on the left front tire of a rear wheel drive vehicle. The technician suspects the camber angle is out of specification. All these characteristics of camber are true EXCEPT:

  • A. Negative camber causes wear on the tires inside tread.
  • B. An out of specification camber angle will result in a steering pull condition.
  • C. The vehicle will pull to the side with the most positive camber.
  • D. Camber is not included in the included angle.

23.

Answer A is wrong. This is an except question. If the camber is negative, the tire will wear on the inside tread.

Answer B is wrong. Out of specification camber will result in a pull condition. Visually inspect the vehicle for a bent control arm, spindle or strut.

Answer C is wrong. The vehicle will pull to the side with the most positive camber.

Answer D is correct. The camber angle is included with the SAI to equal the included 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.
