What is a Wheel Bearing? Why do they need to be replaced?

When it comes to your vehicle’s safety and performance, wheel bearings play a crucial role. These small but mighty components are what enable your wheels to rotate smoothly and with minimal friction, which is why it’s essential to ensure they’re in good working condition. We’ll explain how a wheel bearing works and why they must be changed periodically.

First and foremost, a wheel bearing is a set of steel balls or rollers that are housed within a metal ring called a race. The bearing is designed to allow the wheel to rotate around an axle while supporting its weight. The steel balls or rollers are positioned between the two races and allow for the smooth rotation of the wheel.

Wheel bearings work under extreme conditions, as they are subject to heat, friction, and vibration, which can cause them to wear out over time. As they wear, the steel balls or rollers can become pitted or damaged, which can lead to a rough ride, unusual noises, and reduced steering control. If left unattended, a worn or damaged wheel bearing can cause the wheel to seize or even fall off, which can result in a serious accident.

The lifespan of a wheel bearing can vary depending on a few factors, such as the quality of the bearing, driving conditions, and maintenance. Generally, a wheel bearing can last anywhere from 100,000 to 150,000 Kilometres, but this can vary. It’s important to have your wheel bearings inspected regularly to ensure they’re in good condition and to catch any issues early.

When it comes to changing a wheel bearing, it’s essential to have it done by a qualified mechanic who has the necessary tools and expertise. The process involves removing the wheel hub and pressing out the old bearing before installing a new one. In some cases, the entire wheel hub assembly may need to be replaced.

Wheel bearings are critical components that allow your wheels to rotate smoothly while supporting their weight. They work under extreme conditions and can wear out over time, leading to reduced performance and safety risks. To ensure your vehicle’s safety and performance, it’s important to have your wheel bearings inspected regularly and to have them changed when necessary. We can help you determine when it’s time to replace your wheel bearings and ensure the job is done right. For a quote call 9987 2818.
