Of the many parts that make up a car, wheel bearings play a fundamental role in its proper functioning and safety. These bearings, which are also known as bushings, are located in each of the wheels of the vehicle and allow them to rotate smoothly, minimizing friction.
Despite its low cost, a part costing only 50 euros can cause serious steering problems if not properly maintained, including squeaking or rubbing noises that warn of possible wear.
A normal car can have about 36 bearings distributed in different areas, the most common being the four located on the wheels. These bearings not only facilitate the rotational movement of the wheels, but also directly influence the durability of the tires and the stability of the vehicle.
Each bearing is made up of rolling elements between two rings, which help transmit rotating loads from the axle to the car’s frame, essential for safe driving.
The main indicator of a worn bearing is noise while driving, which may be accompanied by vibrations in the steering wheel. This deterioration is usually a consequence of the wear of the internal material of the bearing or the entry of dirt and grease, which compromises its operation.
Experts recommend checking these components annually and replacing them if any anomaly is detected, a task that can be carried out even without going to a specialized workshop – although it is always better to have it looked at by an expert to guarantee a good diagnosis of what is happening.
To maximize the life of your wheel bearings, it is essential to avoid certain practices such as overloading the vehicle, using non-standard tire sizes, or driving in a sporty manner. These factors considerably increase the wear of the bearings due to the greater force to which they are subjected, especially on roads with potholes and speed bumps.
In addition to the load and type of driving, modifications to the suspension can also accelerate the wear of these components. Drivers should use caution when driving and maintaining their vehicles, avoiding sudden changes over curbs and ensuring that tires and suspensions are suitable and well maintained.
