release bearing buying guide
Why replace this part?
The clutch release bearing (throw-out bearing) is a ball bearing assembly that slides on the gearbox input shaft guide tube and, when the clutch pedal is pressed, contacts the clutch pressure plate diaphragm spring to disengage the clutch. Although it only contacts the pressure plate during clutch operation, its failure causes noise and complete loss of clutch function. It is always replaced as part of a complete clutch kit.
Signs you need a replacement
- Squealing, chirping, or grinding noise that changes with clutch pedal position
- noise disappears when clutch pedal is fully released or fully depressed
- clutch pedal vibration
- difficulty engaging gears due to incomplete clutch disengagement
- noise worsens progressively over weeks
When to replace
Always replace with the clutch disc and pressure plate — separating these items makes no economic sense given shared labour costs. Typically every 60,000–100,000 miles. Continuous-contact release bearings (common on VAG group vehicles) wear faster as they are always loaded.
