Wheel bearings are critical components that allow the wheels of a vehicle to rotate smoothly with minimal friction. Located inside the wheel hub, they support the vehicle’s weight and enable the wheels to spin freely while maintaining proper alignment. Wheel bearings are built to withstand heavy loads and constant motion; However, over time they can wear out due to heat, moisture or rough road conditions. Signs of a failing wheel bearing include grinding or humming noises, wheel wobble or uneven tire wear. Replacing worn bearings is essential for safe driving, proper wheel function and preventing further suspension or drivetrain damage.
