16.

Answer A is correct. Technician A is correct, the vehicle in the chart is within specifications. Notice the different methods of displaying the vehicle's alignment angles.

Answer B is wrong. The toe is within specifications. An alignment technician will try to achieve the preferred angle of -1/4" and adjust the front toe accordingly.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

17. A vehicle with variable assist steering feels loose only at highway speeds. Technician A says to inspect VSS vehicle speed sensor operation. Technician B says this is caused by reduced pressure to the steering gear. Who is correct?

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

17.

Answer A is correct. These VES or variable effort steering system controller uses the VSS signal. It provides less or lower pressure at highway speeds resulting in a tighter feel. If the wheel feels loose or sloppy at highway speeds, suspect a fault in the VSS, it's circuit or controller.

Answer B is wrong. The pressure varies, it's reduced at highway speeds and increased for parking maneuvers. Excessive assist at highway speeds would be caused by too much pressure for the speed and driving conditions.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

18. A vehicle with a ribbed serpentine belt makes a chirping noise when starting. Technician A says to check the belt with a belt wear gauge. Technician B says proper belt deflection is 1/2 inch per foot of belt span. Who is correct?

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

18.

Answer A is wrong. Both technicians are correct.

Answer B is wrong. Both technicians are correct.

Answer C is correct. Also, if a belt wears excessively on one of the edges, check pulley alignment. A weak belt tensioner will result in a chirping or squealing sound when first starting the engine.

Answer D is wrong. Both technicians are correct.

19. A vehicle has excessive body sway while cornering. Which of the following is MOST likely causing this condition.

  • A. A binding ball joint.
  • B. A worn idler arm.
  • C. Worn control arm bushings.
  • D. Worn stabilizer bar bushings.

19.

Answer A is wrong. A worn ball joint is not likely to cause this condition.

Answer B is wrong. An worn idler arm is not likely to cause this condition.

Answer C is wrong. The worn or mis-adjusted control arm is not likely to cause this condition.

Answer D is correct. The stabilizer bar or sway bar helps control vehicle roll or sway while cornering. Worn and broken sway bar bushings will result in excessive sway while cornering.

20. After replacing a tapered ball joint the technician loosens the castle nut just enough to install the cotter pin. Technician A says this procedure keeps the ball joint from binding. Technician B says a binding ball joint will result in memory steer. Who is correct?

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

20.

Answer A is wrong. Loosening the castle nut will result in a loose ball joint. A loose ball joint will result in a popping noise.

Answer B is correct. Technician B is correct. A binding ball joint will result in memory steer.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
