A Comprehensive Guide on How to Fix Throwout Bearing Noise

The throwout bearing, also known as the clutch release bearing, is a critical component in a manual transmission system. It plays a crucial role in the smooth engagement and disengagement of the clutch by facilitating the movement of the clutch fork and pressure plate.

Over time, throwout bearing noise can develop due to wear and tear, causing discomfort and potential damage to the transmission. In this article, we will delve into the causes of throwout bearing noise and explore the steps to effectively fix this issue.

Causes of Throwout Bearing Noise

Throwout bearing noise can manifest in various ways, including squealing, chirping, or grinding sounds. Several factors can contribute to the development of this noise:

  1. Wear and Tear: The constant friction between the bearing and the clutch components leads to wear over time. As the bearing becomes worn, it can produce noise when moving against other parts.
  2. Lack of Lubrication: Adequate lubrication is essential to minimize friction and noise. Insufficient lubrication can cause the bearing to rub against other parts, resulting in unwanted noise.
  3. Misalignment: Incorrect installation or misalignment of the clutch components, including the throwout bearing, can lead to uneven wear and noise generation.
  4. Contaminants: Dust, dirt, and debris can accumulate in the clutch housing, affecting the smooth operation of the bearing and resulting in noise.

Steps to Stop Throw out Bearing Noise

Before attempting any repairs, it’s important to note that working on a manual transmission system requires a certain level of mechanical expertise. If you’re not comfortable with these tasks, it’s advisable to seek professional assistance. Here’s a step-by-step guide to fixing throwout bearing noise:

1. Diagnose the Issue:

  • Before proceeding with any repairs, confirm that the noise is indeed coming from the throwout bearing. Other transmission components, such as the pilot bearing or input shaft bearing, could also be sources of noise.
  • Engage and disengage the clutch while the engine is running and the vehicle is stationary. Listen for the noise and pay attention to when it occurs.

2. Gather Tools and Materials:

  • Depending on the diagnosis, you may need tools such as wrenches, sockets, a jack, jack stands, and a pry bar.
  • If replacement is necessary, ensure you have a compatible replacement throwout bearing.

3. Lift the Vehicle:

  • Safely lift the vehicle using a jack and secure it with jack stands.

4. Access the Clutch Components:

  • Depending on the vehicle, you may need to remove the transmission, clutch housing, or other components to access the throwout bearing.

5. Replace the Throwout Bearing:

  • Carefully remove the old throwout bearing by detaching any retaining clips or fasteners.
  • Clean the area thoroughly to remove any dirt or debris that could affect the new bearing.

6. Install the New Throwout Bearing:

  • Apply a small amount of high-temperature grease to the inside of the new bearing to ensure smooth operation.
  • Carefully slide the new bearing onto the transmission input shaft or bearing retainer.

7. Reassemble Components:

  • Put back any components that were removed, ensuring proper alignment and torque specifications.

8. Test and Verify:

  • Lower the vehicle, start the engine, and test the clutch engagement and disengagement. Listen for any signs of noise.

9. Lubricate and Maintain:

  • Regularly inspect and lubricate the throwout bearing and clutch components to prevent future noise issues.
  • If you notice any leaks or further noise, address the issue promptly to avoid further damage.

How Long Does a Throwout Bearing Last

The lifespan of a throwout bearing can vary depending on a variety of factors, including the quality of the bearing, the driving conditions, the type of vehicle, and the driver’s habits. Generally, a throwout bearing can last anywhere from 50,000 to 150,000 miles (80,000 to 240,000 kilometers) or more.

However, it’s important to note that some drivers may experience premature wear due to aggressive driving, frequent stop-and-go traffic, or improper clutch operation. Regular maintenance and proper driving habits can help extend the life of a throwout bearing.

If you notice any signs of a failing throwout bearing, such as unusual noises when engaging the clutch or changing gears, it’s recommended to have it inspected and replaced if necessary, as a worn-out throwout bearing can lead to clutch and transmission problems.


Addressing throwout bearing noise is essential for maintaining the optimal performance and longevity of a vehicle’s clutch system. The throwout bearing plays a critical role in engaging and disengaging the clutch, and any noise or issues can indicate underlying problems.

By following the steps outlined in this guide, including identifying the source of the noise, inspecting the clutch components, and performing necessary repairs or replacements, drivers can effectively fix throwout bearing noise.

Regular maintenance and addressing issues promptly are key to preventing further damage and avoiding more extensive and costly repairs down the line. Remember that consulting a professional mechanic is always recommended, especially if you’re unsure about the extent of the problem or the repair process.

With proper attention and care, resolving throwout bearing noise will contribute to a smoother driving experience and the overall health of your vehicle’s clutch system.
