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. A vehicle pulls to the right and makes a clunking sound when the brakes are applied. During an alignment check the technician notices excessive negative caster on the right front wheel. Technician A says this is most likely caused by a seized brake caliper. Technician B says this is most likely caused by worn or missing strut rod bushings. Who is correct?

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

29.

Answer A is wrong. A seized right front brake caliper will cause the vehicle to pull to the left when braking. This would not result in excessive negative caster.

Answer B is correct. Worn strut rod bushings will result in a clunking noise when the brake is applied, because the lower control arm shifts back from a lack of bushing support. Back and forth movement of the strut rod affects a vehicle's caster angle. Some vehicles use the strut rod to adjust caster.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

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.
