Car bearings are essential components for the correct rotation of the wheels and for the stability of the vehicle.
When this component begins to fail, noises, vibrations, and real risks arise that jeopardize the safety of the vehicle.
In this article, understand what bearings are, what the signs of wear are, when they should be replaced, and what precautions to take.
What Are Car Bearings?
Car bearings are mechanical components that allow the wheels to rotate smoothly, as they reduce friction between moving parts and support the weight of the vehicle while driving.
Without car bearings in good condition, the wheel does not rotate evenly, which directly affects the safety, comfort, and stability of the vehicle.
What Do Bearings Do On a Car?
In short, car bearings ensure:
- Smooth wheel rotation;
- Stability when cornering;
- Less tire wear.
What Are The Types Of Car Bearings?
There are several types of bearings for each car wheel, depending on the vehicle model and suspension system.
In general, the main types of bearings for cars are:
1. Plain Bearing
Of all types, the plain bearing is the simplest. As a rule, it is impact-resistant and therefore withstands bumps and sudden movements well.
On the other hand, they are not easily corroded, you just need to choose the right material.
2. Needle Bearing
Like the plain bearing, the needle bearing is impact-resistant and should be installed at a low or medium height.
Although it is not very resistant to longer journeys, this type of car bearing has an enormous load capacity. It is therefore very commonly used on the wheels of heavy vehicles.
3. Double Cone Ball Bearing
The double cone ball bearing is one of the main bearings for cars.
In short, the balls improve the performance of the wheel’s movements, facilitating the vehicle’s displacement.
4. Rigid Ball Bearing
Unlike needle bearings, rigid ball bearings cannot withstand heavy loads, but they offer better displacement thanks to the balls.
According to DIN (German Institute for Standardization), this is the best type of bearing for cars.
What Are The First Signs Of Bearing Failure?
The first sign of wear is when the car bearing makes noise as speed increases, but there are other symptoms that may indicate problems with this component:
- Noise that changes when turning the steering wheel;
- Vibration in the steering wheel or bodywork;
- Play in the wheel when raised.
How Long Does a Wheel And Suspension System Bearing Last?
Durability depends on the quality of the car bearing, as well as road conditions, driving style, and vehicle weight. Under normal conditions, this component can last for several years without problems.
When To Replace Car Bearings?
There is no fixed interval for replacement. On average, a car bearing can last between 100,000 and 150,000 km.
Although this component does not have a replacement interval, it should be replaced:
- When abnormal noises occur;
- After a strong impact on a wheel;
- If play is detected during inspection;
- During other repairs to the axle.
What Happens If You Don’t Replace The Wheel And Suspension System Bearing?
Ignoring a problematic car bearing can cause:
- Increased noise while driving;
- Vibrations in the steering wheel;
- Irregular tire wear;
- Increased braking distance;
- Wheel lock in extreme cases.
In addition, repairs become more expensive over time.
Care To Be Taken For The Proper Functioning Of Wheel And Suspension System Bearings
Since car bearings are sealed, it is not possible to maintain them.
In this sense, there is nothing better than preventing the need to replace them ahead of schedule. To do this:
1. Drive Carefully To Avoid Wear And Tear On The Wheel And Suspension System Bearings
Avoid driving over speed bumps at high speeds or hitting potholes or manholes.
2. Drive On Smooth Roads
Whenever possible, drive on paved roads and avoid uneven surfaces, such as dirt roads or uneven pavement. This will prevent your car from being exposed to excessive vibration that can damage the bearings.
3. Avoid Off-Road Adventures
Although they may seem fun, do not expose your city or family car to jumps caused by off-road adventures.
This can lead to a very high bill, which includes not only the bearings, but also the suspension and tires.
4. Check The Vehicle’s Lubrication System
By ensuring that your car is properly lubricated, you are preventing causes that, in most cases, cannot be avoided.
5. Avoid Moisture
Although manufacturers already include moisture seals, the truth is that these may not be sufficient to resist liquids. Therefore, avoid driving through puddles when it rains.
How Much Does It Cost To Replace Bearings In a Car?
The price of a car bearing varies depending on the position of the wheel, the type of bearing, and the vehicle model.
As a rule, the price of a front wheel bearing is higher than that of a rear wheel bearing, as it is subject to greater stress, such as steering, braking, and engine load.
However, in cars with more complex systems or hub-integrated brakes, the cost may be similar to that of the front.
As a general rule, the price of bearings varies between tens of euros. A bearing kit, on the other hand, costs around hundreds of euros.
How Much Does It Cost To Change The Bearings In The Wheel And Suspension System?
The total cost includes the price of the bearing, as well as labor and any steering alignment. Therefore, the cost can easily run into hundreds of euros.
Since replacing this component is a technical operation that requires the right tools and experience, it is recommended that you take your car to a repair shop.
