b. Technician B only

c. Both A and B

d. Neither A nor B

To determine

The technician with correct approach.

Explanation

Given information:

While discussing different abnormal clutch noises:

Technician A says that pilot bushing noises are most noticeable in cold weather and usually occur when the pedal is being depressed and the transmission is in neutral.

Technician B says that release bearing noise is most noticeable when the transmission is in neutral and occurs when the clutch pedal is depressed and stops when the pedal is fully released

Pilot bushing is used to provide support to the transmission input shaft outer end. This input shaft helps in transmitting power from the engine to the transmission and it is meshed with clutch disc. If the shaft changes its position, a pilot busing is used to provide support and hold it in center. It helps in positioning the input shaft central to the pressure plate. It is present in the center of the flywheel. The pilot bushing or bearing can be of any type for example- ball type, roller type and needle type...
