The driveshaft is critical to the performance of your Porsche. Immense power is created by your car’s engine through various processes of combustion. However, it is of no use if it is not transferred to the wheels.

The driveshaft is connected to the sections of the drivetrain that help to conduct torque and rotation. It is a long cylindrical tube powered by your Porsche’s powerful engine. When the driveshaft spins, it transfers torque to the wheels, which then makes the wheels spin. It is held in place by the center support. Let’s take a look at why the driveshaft can fail.

Causes of a Malfunctioning Driveshaft

• Road Hazards: Due to the placement of the driveshaft, under the car’s undercarriage, it is constantly at risk of damage from road hazards. Debris like blown tires, boards, and other damaging material can strike under your car causing damage to the driveshaft and the support system.
• Irregular Check-ups: Normal wear and wear can be a reason for the failure of the driveshaft. However, that is generally a result of poor maintenance of the car. Regular inspections are extremely important because the technicians can recognize and correct any issues before they arise.
• Defective Design: All components of a Porsche are designed with great precision and scrutiny. However, sometimes a component can slip through the quality check. This is also why it is important to be regular with the maintenance so the technicians can inform you if the driveshaft has a defective design and so they can fix it without you facing any issues.
• Center Bearing Mount: This component is set in rubber and supports the CV joint and propshaft. Due to the rubber being soft and pliable material, it gives out quickly and worms out faster due to the vibrations that shake the CV. Over time, it causes a failure in the driveshaft.
• Driveshaft Support Cracking: This can be caused by a dried-out support mount. If the driveshaft support cracks, then the driveshaft of your Porsche will not function properly.
• Driveshaft Support Failure: This can be caused by dry CV joints and play a part in the failure of the driveshaft.
• Worn-Out Rollers: This can lead to increased friction, excessive shaking, and sometimes even loss of control over the vehicle. This is generally characterized by grinding noises.

Warning Signs of a Faulty Driveshaft

• Acceleration: During acceleration, if the driveshaft support shudders, it is a sign of a failed driveshaft support. It will cause the driveshaft to flex incorrectly which will lead to shakes and tremors. If this issue goes unchecked, it can become even severe and result in the driveshaft making contact with the underside of your Porsche. This will damage both the driveshaft and the car’s chassis.
• Unusual Noises: If there are noises like howling and squealing coming from your car during acceleration, it is most likely pointing to a faulty driveshaft.
• Rubber support bearing: A driveshaft can fail if the rubber support bearing cracks or wears down. It is often accompanied by a whining
• Center Support Mount: The disintegration of the component’s center support mount is the reason for a failing driveshaft about 80% of the time. However, it can also be caused by other factors, so it’s best if you let our skilled technicians do the work for you.
• Turning of the Wheels: If you face difficulty in turning your Porsche, then it could be indicating a malfunctioning driveshaft.

It is vital to take immediate action if a failure in the driveshaft is suspected. If it is delayed or ignored it could lead to extensive damage to your Porsche and much more expensive repairs.
