41.

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.

42. Technician A says that loose power steering rack bushings result in vehicle wander. Technician B says worn rack bushings cause changes in toe. Who is correct?

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

42.

Answer A is wrong. Loose or worn rack bushings will result in vehicle steering wander.

Answer B is wrong. Loose or worn rack bushings will result in excessive rack movement. This movement can change the tie rod adjustment after hitting a bump. This is also known as bump steer.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

43. There is noticeable wear on the left front tire of a rear wheel drive vehicle. The technician suspects the camber angle is out of specification. All these characteristics of camber are true EXCEPT:

  • A. Negative camber causes wear on the tires inside tread.
  • B. An out of specification camber angle will result in a steering pull condition.
  • C. The vehicle will pull to the side with the most positive camber.
  • D. Camber is not included in the included angle.

43.

Answer A is wrong. This is an except question. If the camber is negative, the tire will wear on the inside tread.

Answer B is wrong. Out of specification camber will result in a pull condition. Visually inspect the vehicle for a bent control arm, spindle or strut.

Answer C is wrong. The vehicle will pull to the side with the most positive camber.

Answer D is correct. The camber angle is included with the SAI to equal the included angle.

44. 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

44.

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.

45. Two technicians are discussing an air bag solenoid located on the top of the air bag. Technician A says this valve is used to inflate the air bag. Technician B says this valve is used to deflate the air bag. Who is correct?

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

45.

Answer A is wrong. The solenoid receives a signal from the ECM to inflate the air bag to raise the vehicle. A faulty air bag solenoid can prevent the vehicle's suspension from raising.

Answer B is wrong. The solenoid receives a signal from the ECM to deflate the air bag to lower the vehicle. A faulty air bag solenoid can prevent the vehicle's suspension from lowering as well.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.
