Product Description
Wheel hub bearings are designed to withstand both radial (side-to-side) and axial (front-to-back) loads, which are common in vehicle applications. They are subjected to various forces, including the vehicle's weight, acceleration, braking, and cornering forces. Therefore, high-quality wheel hub bearings are vital for ensuring safe and reliable vehicle operation.
Over time, wheel hub bearings can wear out or become damaged due to factors such as excessive use, improper installation, contamination, or exposure to harsh conditions. When a wheel hub bearing starts to fail, it may produce symptoms such as excessive noise, vibration, play in the wheel, or uneven tire wear. If any of these signs are noticed, it is essential to have the wheel hub bearing inspected and, if necessary, replaced by a qualified mechanic.
