Wheel bearings are crucial elements in a vehicle's wheel assembly, enabling smooth and efficient rotation of the wheels while supporting the weight of the vehicle. They consist of a set of steel balls or rollers held together by a metal ring, enclosed within a protective housing. Their primary function is to reduce friction between the wheel hub and the axle, allowing the wheels to spin freely with minimal resistance.
Wheel bearings also help maintain wheel alignment and stability, ensuring safe handling and optimal performance while driving. Over time, wheel bearings may wear out due to factors like high mileage, heavy loads, or improper maintenance, leading to symptoms such as noise, vibration, or irregular tire wear.
