A damaged pilot bearing may cause a rattling or growling noise when which of the following conditions exist?

In a hydraulic clutch system, the clutch fails to disengage properly when the clutch pedal is fully depressed. The cause of this problem might be which of the following? A. Less than specified clutch pedal freeplay B. Air in the clutch hydraulic system C. Worn clutch facings D. A scored pressure plate
