Question

a noise is heard on a vehicle equipped with a manual transmission. the noise only occurs when the clutch pedal is completely depressed, and the noise goes away when the pedal is released. technician a states that it could be a failed pilot bearing. technician b states that to replace a pilot bearing, the transmission will have to be removed. who is correct?

a. technician a

b. technician b

c. both technician a and technician b

d. neither technician a nor technician b

Explanation:

1. For Technician A: A failed pilot bearing in a manual transmission often produces noise when the clutch pedal is fully depressed (as the bearing is in operation then) and the noise stops when the pedal is released. This is a typical symptom of a faulty pilot bearing.
2. For Technician B: To replace a pilot bearing, the transmission needs to be removed because the pilot bearing is located behind the clutch, and accessing it requires taking out the transmission.

So both Technician A and Technician B are correct.

Answer:

c. Both Technician A and Technician B
