ASE A4 Steering Suspension Practice Test

26. A vehicle with a power rack and pinion steering system is binding during turns. Which of the following is LEAST likely to cause this condition.

  • A. Strut mount bearing.
  • B. Worn rack bushings.
  • C. Worn rack and pinion gear.
  • D. Lower ball joint.

26.

Answer A is wrong. Strut mount bearings can loose lubrication and bind while cornering.

Answer B is correct. Worn rack bushings cause a vehicle to wander. Notice the other three options cause binding.

Answer C is wrong. A worn power steering rack gear can bind causing difficulty while cornering.

Answer D is wrong. A faulty or dry ball joint will result in binding felt while cornering.

27. Two technicians are discussing excessive wear on the inside tread of a tire. Technician A says an out of specification caster angle will cause this type of wear. Technician B says an out of specification camber angle will cause this type of wear. Who is correct?

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

27.

Answer A is wrong. Caster is considered a non tire wearing angle.

Answer B is correct. Out of specification camber will result in inside or outside tire wear.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

28. After installing a power steering gear, the vehicle's air bag light is illuminated. Technician A says the vehicle's wheel alignment needs to be adjusted to repair this light. Technician B says the clockspring has been damaged. Who is correct?

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

28.

Answer A is wrong. The vehicle must be aligned, but replacing the rack should not illuminate the air bag light.

Answer B is correct. If the wheel is not held firmly while installing a steering gear, the clockspring will break creating an open in the air bag circuit.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

29. There’s a squeak in the steering column when the steering wheel is turned in either direction. All of the following components will result in a noisy steering column EXCEPT.

  • A. Steering coupling
  • B. Clockspring
  • C. Steering column bearings
  • D. Horn switch

29.

Answer A is wrong. The universal steering coupling connects the stub of the steering column to the steering gear. They become loose or bind resulting in excessive noise

Answer B is wrong. The clockspring provides a connection between the steering column the SRS air bag and the wheel’s accessories.

Answer C is wrong. Steering column bearings cause a growl or squeak when worn. There’s a bearing located at the top and bottom of the steering shaft.

Answer D is correct. The horn switch is stationary when the wheel is turned. It’s located in the steering wheel. A faulty horn switch likely has burned contacts and will hamper operation of the horn but would not make noise when the wheel is turned.

alignment chart

30. The vehicle in the alignment chart pulls to the right. Technician A says this is because a vehicle will pull to the side with the most camber. Technician B says this is because the vehicle's caster angle is out of specifications. Who is correct?

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

30.

Answer A is correct. The vehicle in the chart has excessive camber, beyond .5 in the specifications on the right front wheel. This will cause the vehicle to pull to the right, because a vehicle will pull to the side with the most camber.

Answer B is wrong. The caster readings are within specifications.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.
