A wheel hub bearing unit is an important part of a car’s wheel assembly, enabling wheels to turn freely and playing a crucial role in the safety and handling characteristics of a vehicle. Comprised of precision- manufactured bearings, seals and sensors in one pre-assembled unit, a wheel hub bearing unit is critical to performance, from the smoothness of the ride, to fuel efficiency, to the integrity of anti-lock braking systems (ABS).
While at cruising speeds a definite growling noise along with vibration will be felt in the steering in the case of the front and in the vehicle seat or floor in case of the rear. That is what usually alerts the driver to a wheel bearing issue. When steering and changing lanes on the roadway, sometimes a change in growling pitch and vibration might be noticed and will alert the driver to a bearing issue as well. In severe cases a low brake pedal will be due to a wheel bearing issue. What cause damage to a Wheel Bearing?
