Car owners with manual transmissions may experience a similar occurrence – an unusual vibration when the clutch is let out. Why is this? We will address what could go wrong with your car’s clutch and how to immediately identify the problem.

1. The master or slave cylinder might start to leak.  Hydraulic and cable-operated are two kinds of clutches. Most cars now have hydraulic, which rely on fluid from the cylinders to actuate the clutch.  If the master or slave cylinder starts to lose fluid, it can become impossible to produce hydraulic pressure.

How to detect the problem: If the cylinders are leaking, you will notice fluid pooling up under your car. Or you may experience an unusual odor caused by fluid dripping on the exhaust.

2. The throwout may wear out.  The throwout bearing actuates the pressure plate.  It rides on the input shaft for the transmission.  Because it’s constantly spinning, it can become worn down and lose lubrication.

How to detect the problem: If you hear a squeaking sound when the car is running, but the sound disappears as the clutch is activated, it may be due to a damaged bearing.

 3. The clutch disc may be worn out.  The clutch disc is splined to the shaft of your transmission. The disc will likely wear out over time due to reckless driving habits.

How to detect the problem: When the clutch disc becomes worn out, it will cause the clutch pedal to release higher. In this situation, it may be difficult for a car to accelerate under a heavy load.

4. The flywheel may become warped.  The flywheel is bolted to the end of the crankshaft, similar to how rotors are connected to axles. Over time, the flywheel can overheat causing it to warp.

How to detect the problem: As the flywheel’s surface becomes uneven, you may experience vibrations as you let out the clutch.

5. Your pressure plate may be worn out.  The pressure plate clamps the clutch disc to the flywheel.  Since it is one of the hardest working parts of your clutch, it can wear down easily.

How to detect the problem: As with your flywheel, a damaged pressure plate can also result in vibration as the clutch is let out.
