The clutch release bearing is an integral part of a manual transmission vehicle, and its health directly affects the performance of the clutch and the safety of the vehicle. The following are some of the possible symptoms of clutch release bearing failure and their impact on vehicle performance:

1. Strange noise:

   - When the clutch pedal is pressed, abnormal sounds such as “rustling”, “squeaking” or “clicking” may be heard, which may be caused by bearing wear, poor lubrication or damage to the parts These sounds may be caused by worn bearings, poor lubrication, or damaged parts rubbing against each other.

   - These sounds may be caused by worn bearings, poor lubrication or friction between damaged parts. The abnormal sounds may appear at different stages of pedal pressing, sometimes they can be heard when the pedal is lightly pressed, and sometimes they need to be pressed to the bottom before they can be heard.

2. Abnormal pedal feel:

   - The clutch pedal may feel heavy or difficult to depress. This may be caused by bearing sticking, insufficient lubrication or damage to related parts.

   - Poor pedal return, i.e., failure to return quickly and completely to the initial position after releasing the pedal, may also be an indication of bearing failure.

3. Incomplete clutch release:

   - Damage to the clutch release bearing may result in incomplete clutch separation, affecting the normal operation of the clutch and leading to problems such as difficulty in shifting gears, increased engine speed but no increase in vehicle speed.

4. Weakness of vehicle driving:

   - Due to incomplete clutch disengagement or slippage, the power of the engine cannot be completely transferred to the transmission, which leads to weak vehicle driving and reduced acceleration performance.

5. Difficulty in shifting gears:

   - When shifting gears, you may feel increased resistance or not be able to shift into gear, which is also a manifestation of clutch release bearing failure.

6. Visual inspection:

   - Physical damage to the bearing, such as wear, corrosion or deformation, may be noted during inspection.

7. Lubrication problems:

   - Lack of lubrication can cause the bearing to dry out, increasing friction and noise.

8. Overheating:

   - Clutch release bearings may overheat and if left untreated may lead to further damage.

Conclusion:

If you notice any of these symptoms, have your vehicle inspected by a professional mechanic promptly. Regular maintenance and timely repairs can help prevent further damage and ensure your vehicle runs smoothly and safely. Failure of the clutch release bearing not only affects the driving experience, but can also lead to more serious problems with the clutch and drivetrain. Therefore, care and maintenance should be taken in daily use to avoid damage to the clutch system from bad driving habits such as prolonged half-clutch operation and overloaded driving.
