These small components have the vital function of allowing free rotating of the wheels on your vehicle. Common faults in this component occur when seals become damaged or broken, allowing greased to escape and wearing elements such as air, dirt or water to get in. Due to the assembly of this contained unit, if a seal breaks the whole unit will often require replacing, as there will be no indication as to the extent of the internal damage to the wheel bearing cylinder.
Spotting a Wheel Bearing Fault
Spotting faults with your wheel bearings can be easy. The most obvious sign is a whistling or rumbling noise coming from your wheel area. The noise is prone to change through corners and turns. In addition to the noise, your vehicle may stray and pull when travelling in a straight line.
