ASE A4 Steering Suspension Practice Test

26. The steering wheel of a vehicle with a power rack and pinion steering system binds while turning. 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 wear and lose lubrication. This wear causes them to bind while cornering. A worn strut mount also causes a thunking sound when going over bumps in the road.

Answer B is correct. Worn rack bushings aren't likely to bind; they affect the toe and cause a vehicle to wander.

Answer C is wrong. A worn power steering rack gear can cause binding.

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

27. Technician A says an excessive, out-of-specification camber angle results in steering pull and tire wear. Technician B says a misaligned engine cradle on a front-wheel-drive vehicle affects its camber angles. Who is correct?

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

27.

Answer A is wrong. An incorrect camber angle results in steering pull and tire wear. The tires will wear on the edges, and the vehicle will pull to the side with the most positive camber.

Answer B is wrong. A misaligned or loose engine cradle affects the vehicle's wheel alignment angles. The engine cradle has the lower control arms attached.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

28. The vehicle's airbag warning light illuminates after replacing the rack and pinion power steering gear. Technician A says to adjust the alignment angles to repair this light. Technician B says to check for a damaged clockspring. 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 and pinion power steering gear should not illuminate the airbag light.

Answer B is correct. Use a steering wheel lock to hold the wheel while disconnecting the steering column universal joint; the steering wheel can spin, causing the clockspring to break, resulting in the airbag or SRS warning light.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

29. The left front wheel sits back 1 1/8 inches further than the right. Technician A says this is an acceptable setback designed into the vehicle to compensate for crowned roads. Technician B says a vehicle will drift towards the side with the most setback. Who is correct?

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

29.

Answer A is wrong. 1 1/8 inches is an excessive setback; most vehicles have little (~1/4 in or less) or none. This vehicle may have been in a collision. Look for a bent part and other front-end damage.

Answer B is correct. A vehicle drifts to the side with the most setback.

Answer C is wrong. Some wheel setback can be factored in to compensate for road crowning.

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 pulls to the side with the most camber. Technician B says this is because the right front caster angle exceeds specifications. Who is correct?

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

30.

Answer A is correct. The vehicle in the chart has excessive camber, beyond the .5° tolerance in the specifications on the right front wheel. It causes the vehicle to pull to the right because a vehicle pulls 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.
