  • A. Camber
  • B. Wheel Balance
  • C. Toe
  • D. Caster
alignment chart

1.

Answer A is wrong. The camber angle is within specifications. Camber is a tire wearing angle that will cause a pull to the side with the most positive camber.

Answer B is wrong. Out of balance tires cause a vibration at speeds above 45 mph, but after viewing the chart the caster is clearly out of specifications, and too much positive caster will result in wheel shimmy.

Answer C is wrong. The toe is within specifications. Answer D is correct.

Answer D is correct. Too much positive caster will result in wheel shimmy.

2. A vehicle with a power rack and pinion steering system doesn't return to center after completing a turn. Technician A says an incorrect caster angle will cause this condition. Technician B says a binding lower ball joint would have no affect on steering wheel return to center. Who is correct?

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

2.

Answer A is correct. Cars and light trucks typically have a positive caster setting, this helps steering wheel return to center.

Answer B is wrong. A binding ball joint will affect the steering wheel's ability to return to center. It will also result in a clunking noise while turning the wheel.

.Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

3. The LEAST likely to result in memory steer is a binding:

  • A. Ball joint.
  • B. Steering gear.
  • C. Upper strut mount.
  • D. Wheel bearing.

3.

Answer A is wrong. This is a LEAST likely question. A binding ball joint causes memory steer.

Answer B is wrong. A binding steering gear causes memory steer.

Answer C is wrong. A binding upper strut mount causes memory steer.

Answer D is correct. Wheel bearings cause a growling noise that increases with speed and changes pitch during turns. If a wheel bearing were binding, there would be a grinding sound when rotating the wheel.

4. Two technicians are discussing struts on a front wheel drive vehicle. Technician A says some struts have a camber lobe adjustment. Technician B says a worn strut tower will make excessive noise when going over bumps. Who is correct?

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

4.

Answer A is wrong. Both Technicians are correct.

Answer B is wrong. Both Technicians are correct.

Answer C is correct. Some struts have an eccentric camber lobe adjustment. A bad strut tower will make a thumping noise when going over bumps.

Answer D is wrong. Both Technicians are correct.

5. Technician A says a worn idler arm has no affect on a vehicle's total toe setting. Technician B says the center link is used in parallelogram linkage systems. Who is correct?

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

5.

Answer A is wrong. A bad idler arm will affect toe settings.

Answer B is correct. The center link is found on parallelogram linkage systems.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
