The driveshaft of the car: what it is, how it works and what to do if it breaks


Welcome to, where we are passionate about the motor world and we are here to answer all your questions. In this article, we are going to talk about the drive shaft of the car, its operation, what to do in case of a breakdown and the associated dangers. Read on for all the information you need!

What is the bearing of the car?

The bearing, also known as the transmission shaft, is a fundamental piece in the transmission system of a vehicle. Its main function is to transmit the power generated by the engine to the wheels, thus allowing the movement of the car. It is made up of a series of axes and joints that allow the necessary flexibility to adapt to the irregularities of the terrain.

How does the shield work?

The bearing is connected to the gearbox at one end and to the wheels at the other. When the engine generates power, it is transmitted through the driveshaft to the wheels, allowing them to move. The driveshaft must be strong enough to withstand the forces generated while driving and flexible enough to adapt to the movements of the wheels.

What happens if the bearing breaks?

If the driveshaft breaks while you're driving, chances are you'll lose traction on the affected wheels. This can cause the car to become unmanageable and difficult to control, especially when cornering or in emergency situations. In addition, a bad drive shaft can damage other components in the drive system, which can result in costly repairs.

How to detect faults in the bearing?

There are several symptoms that may indicate a fault in the driveshaft of the car. Some of the most common are:

  • Vibrations or strange noises coming from the bottom of the vehicle.
  • Problems changing gears or difficulty accelerating.
  • Sudden movements or instability in direction.
  • Uneven tire wear.

If you experience any of these symptoms, it is important that you go to a specialized workshop to check the state of the bearing and make the necessary repairs.

What is the danger of driving with a broken bearing?

Driving with a broken driveshaft can be extremely dangerous. In addition to loss of traction and difficulty controlling the vehicle, a broken driveshaft can cause additional damage to other driveline components. This can result in more serious and expensive breakdowns, as well as emergency situations on the road. Therefore, it is essential to repair or replace the driveshaft as soon as possible to ensure driving safety.

What breakdowns can the transmission bellows cause?

The transmission bellows, also known as the driveshaft bellows, is a piece of rubber that protects the joints of the driveshaft. If the bellows breaks or becomes damaged, it can allow dirt and moisture to enter, which can lead to premature seal wear and loss of lubrication. This can result in bearing failures, such as broken seals or lack of proper lubrication, which will affect the performance of the drive system.

Frequent questions

1. How much does it cost to repair a broken bearing?

The cost to repair a broken shaft can vary depending on the make and model of the car, as well as the severity of the damage. In general, the price can range between 200 and 1000 euros, including labor and the necessary parts. It is important to go to a reputable garage to get an accurate estimate and to ensure that quality parts are used.

2. How long does it take to repair a bearing?

The time required to repair a bearing depends on several factors, such as the availability of spare parts and the workload of the workshop. On average, a bearing repair can take between 2 and 4 hours. However, in more complex cases or if replacement of other parts is required, the repair time may be longer. It is advisable to check with the workshop to obtain an accurate estimate of the time required.


In summary, the drive shaft of the car is a fundamental piece in the transmission system that allows the transmission of power from the engine to the wheels. If it breaks, it can cause loss of traction and damage other components in the drive system. It is important to be attentive to the symptoms of failure and go to a specialized workshop for repair. Do not forget that driving with a broken shaft can be extremely dangerous. Keep your car in good condition and enjoy safe driving!
