ASE A3 Manual Drive Train and Axles

31. There is a chirping sound as the clutch pedal is depressed. Technician A says it could be a worn clutch release bearing. Technician B says the sound is a worn transmission synchronizer. Who is correct?

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

31.

Answer A is correct. A chirping clutch release or throw out bearing will make a squeal when the bearing contacts the pressure plate diaphragm fingers.

Answer B is wrong. Technician A is correct. A worn synchronizer would affect a certain gear range. A clutch release bearing would be heard when the clutch pedal is depressed.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

32. Two technicians are discussing driveline seals. Technician A says repeated extension housing seal failure could be caused by a pitted axle slip yolk. Technician B says a bent axle will cause axle seal leakage. Who is correct?

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

32.

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. Repeated extension housing seal failure can be caused by a pitted slip yolk. A bent axle will also cause axle seal leakage.

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

33. While shifting a part time 4WD vehicle from 2H to 4H, the indicator light flashes and the vehicle remains in 2H. Technician A says this is caused by a faulty planetary gearset. Technician B says this could be caused by a faulty shift motor. Who is correct?

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

33.

Answer A is wrong. Technician B is correct. The planetary gearset, usually located between the input shaft and the drive sprocket, provides a lower gear ratio, allowing the vehicle to be shifted into (4L). The planetary gearset alters gear ratio. It does not engage the front axle for 4WD.

Answer B is correct. A fault shift motor will prevent front axle engagement. This would result in the vehicle remaining in 2H and the indicator light flashing, indicating a problem to the driver.

Answer C is wrong. Many of today’s transfer cases are electronic and require a controller.

Answer D is wrong. Technician B is correct.

34. Technician A says a clutch start switch is normally closed when the clutch pedal is released. Technician B says the clutch start switch is designed to complete the circuit between the ignition switch and the starter solenoid. Who is correct?

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

34.

Answer A is wrong. The clutch start switch is normally open when the clutch pedal is released.

Answer B is correct. It's normally open and closes to complete the circuit when the pedal is depressed.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

35. A squeal is heard from the clutch housing only when the clutch pedal is depressed completely to the floor. Technician A says this could be worn counter shaft bearings. Technician B says the squeal is from a faulty pilot bearing. Who is correct?

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

35.

Answer A is wrong. Counter shaft bearings would make a noise whenever the transmission is operating.

Answer B is correct. A worn pilot bearing will make the most noise when the pedal is completely depressed and the transmission's input shaft and the engine's crankshaft are rotating at different speeds.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
