About this product
The CORAM release bearing (C0004) is a professional-grade replacement component engineered for long service life and reliable operation across all conditions your vehicle encounters. Verified to fit FIAT models. All compatibility data is cross-checked against the TecDoc database — select your vehicle to confirm the part matches your specific engine and year. This part supersedes original equipment references: 1850282189, 262583, 264918, 4304521 and 14 more. Matching these numbers confirms a like-for-like replacement with no loss of function. CORAM is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price. Every part is dispatched from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.
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.

This CORAM release bearing is available for £19.99. Release bearing prices vary depending on brand, specifications, and vehicle compatibility. CORAM parts offer a balance of quality and value, backed by our 14-day money-back guarantee.
How do I know when to replace my release bearing?
Listen for a squealing or rumbling noise that appears when the clutch pedal is depressed and disappears when released. This noise points specifically to the release (thrust) bearing and should not be ignored.
What tools do I need to replace a release bearing?
Tools needed: gearbox jack, circlip pliers (some designs), socket set, clutch input shaft grease. Difficulty: Professional recommended. Safety warning: Always replace the release (thrust) bearing whenever the clutch is replaced -- re-doing this job to replace only the bearing costs the same in labour as doing it right the first time.
