Manual Transmissions and Clutch

Problem

Excessive clutch noise

Possible Cause

1. A bad clutch shaft pilot bearing will make a high pitched squeal when the clutch is disengaged and the transmission is in gear or within the first 2″ of pedal travel.
2. Noise from the clutch linkage is a clicking or snapping that can be heard or felt as the pedal is moved completely up or down.
3. Transmitted engine noises are amplified by the clutch housing and heard in the passenger compartment. They are usually the result of insufficient pedal free-play.

Remedy/Repair

1. The bearing must be replaced.
2. This usually requires lubrication.
3. Manipulating the clutch pedal.
