Cartoq.com also lists shuddering, chirping or grinding noises and rough shifting as warning signs of a bad clutch. Shuddering is when the driver feels excessive shaking or vibration upon releasing the clutch pedal, particularly at low speeds. Shuddering is frequently caused by contamination of the clutch disk by substances like grease, oil or even water.
Chirping or grinding noises that come and go as the driver presses in and releases the clutch pedal are indicative of a worn clutch release bearing. Cartoq.com warns that ignoring such sounds may lead to permanent damage to other clutch components.
