ASE A4 Steering Suspension Practice Test

36. A light truck's left rear leaf spring has a broken center bolt. Technician A says this will affect the vehicle's thrust angle. Technician B says an incorrect thrust angle will affect the centering of the steering wheel. Who is correct?

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

36.

Answer A is wrong. Both Technician A and B are correct.

Answer B is wrong. Both Technician A and B are correct.

Answer C is correct. A sagging or damaged leaf spring, broken center bolt, or shackle results in axle offset and changes the thrust angle. The trust angle also affects the centering of the steering wheel.

Answer D is wrong. Both Technician A and B are correct.

37. A technician is attempting to balance a wheel on a vehicle with a vibration at highway speeds. The wheel will not balance even after adding weights in several places. Technician A says to continue adding weights up to 10 ounces. Technician B says to dismount the tire from the rim and inspect the inside for liquid or debris. Who is correct?

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

37.

Answer A is wrong. The tire most likely has liquid flat repair or liquid from an unpurged compressor. Each time the technician spins the wheel, the liquid settles in a different place, requiring a weight at a different location on the rim. The technician should not just keep adding weights up to 10 ounces.

Answer B is correct. If a wheel remains unbalanced after several attempts, dismount the tire and inspect the inside for liquid or debris.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

38. A vehicle's front tires have feathered treads. What is the MOST likely cause of this condition?

  • A. The caster setting.
  • B. The toe setting.
  • C. Worn struts.
  • D. The camber setting.

38.

Answer A is wrong. A misadjusted caster setting will not likely affect tire wear.

Answer B is correct. An incorrect toe setting causes angled wear and feathered tire treads.

Answer C is wrong. Bad struts cause a choppy scalloped tire.

Answer D is wrong. A bad camber setting will cause wear on one shoulder of a tire or the other.

39. A vehicle has a noticeable difference in vehicle ride height between the driver and passenger side. Technician A says a weak variable-rate coil spring can affect a vehicle's ride height. Technician B says weak strut inserts result in this condition. Who is correct?

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

39.

Answer A is correct. A sagging coil spring, suspension airbag, or leaf spring causes a difference in vehicle ride height.

Answer A is wrong. Perform a bounce test on the shocks to see if they oscillate, and test drive the vehicle to see if it floats and leans excessively around corners. Bad shocks and struts result in cupped and scalloped tires.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

40. A vehicle with a variable-assist power steering system is speed-sensitive and feels sloppy at highway speeds. Technician A says the variable-assist steering system is not reducing hydraulic pressure at higher speeds. Technician B says variable-assist steering provides maximum pressure while performing parking maneuvers. Who is correct?

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

40.

Answer A is wrong. The variable-assist power steering system offers maximum pressure while performing parking maneuvers and reduced pressure at highway speeds.

Answer B is wrong. It is typically accomplished by controlling and varying the steering gear or rack pressure.

Answer C is correct. When these systems fail, the steering will feel speed-sensitive and sloppy at highway speeds.

Answer D is wrong. Both technicians are correct.
