Throw-Out Bearing Failure

Vehicles with manual transmissions have a unique set of maintenance issues to consider. The throw-out bearing is one piece of the clutch assembly that can wreak havoc on your transmission if left unchecked. Knowing the signs of impending bearing failure can save you money and ensure your car runs smoothly.

 

How Throw-Out Bearings Work

 

A throw-out bearing, also known as a clutch release bearing, is a key component of the mechanism that releases the clutch in a standard vehicle to temporarily disengage the engine from the manual transmission when the driver shifts gears.

 

When the clutch is engaged, the throw-out bearing moves to the flywheel, where it pushes the pressure plate’s release levers against the pressure plate’s spring. This action disconnects the engine from the wheels so that the vehicle can be shifted into a different gear.

 

Once the clutch pedal is disengaged, the clutch release bearing returns to its starting position and reconnects the engine’s power to the wheels through the transmission.

 

Where Is the Throw-Out Bearing Located?

 

The throw-out bearing can be found between the clutch fork and the pressure plate fingers in the clutch assembly of the car transmission.

 

Throw-Out Bearing Failure Symptoms

 

Unusual Noises When Engaging the Clutch Pedal

 

When the throw-out bearing begins to wear down, drivers will typically hear grinding or rattling sounds when depressing the clutch pedal. If the sounds then stop when the clutch is released, this is a common indication that the clutch release bearing is in need of replacement.

 

Clutch Pedal Feels Stiff

 

The more worn down the release bearing is, the harder it will become to depress the clutch pedal. When the clutch pedal begins to require increased force to engage and feels stiff, this is a sign that the throw-out bearing is in danger of failing.

 

Clutch Pedal Vibrates

 

The clutch pedal should engage smoothly when depressed. If there are vibrations when pressing the clutch pedal, this is a sign that the throw-out bearing is in its end stages of useful life.

 

Gear Shifting Difficulties

 

When the release bearing is wearing down, it will make it difficult to shift gears when the clutch is engaged. You will notice that the gear shift is harder to move, and you may notice a grinding sound as you are shifting. This means it’s time to have some maintenance performed on your vehicle before you can’t shift gears at all due to a total clutch failure.
