Wheel bearings play an important role within the drivetrain of any vehicle, as they provide the first connection between the moving and static areas of the car. A bearing – in its simplest form – is a friction reduction device placed within something like a wheel to aid efficiency of rotation. This is achieved as rolling produces much less friction force than sliding.
Symptoms of a Worn Wheel Hub Bearing
Signs of a worn wheel hub bearing vary in severity.Noise is a classic sign of a bad wheel bearing or wheel hub bearing. Here are some indicators of a worn wheel hub bearing or other wheel-end damage: 1. Grinding when the vehicle is in motion. There is mechanical damage in a wheel-end system. Related to a bearing, it means a loss of integrity such as roller or raceway damage. The noise is normally heard when turning or when there is a shift in load.
2. Humming, rumbling or growling. These noises are normally associated with tire, electrical or drivetrain components. If bearing-related, the noise or vibration is present when driving in a straight line, but intensifies when turning the steering wheel slightly to the left or right. Typically, the side opposite the rumbling is the defective side. 3. Wheel vibration and/or wobble. This is generally associated with a damaged or worn tire, wheel or suspension component or severe chassis misalignment. When related to the hub or bearing, this normally indicates the loss of clamp or a bearing with extreme mechanical damage. It also can occur when lug nuts are not properly torqued. 4. Abnormal side pull when brakes are applied. This is normally indicative of a defective caliper or equalizer, but it also can be a sign of worn brakes or rotors. However, severe looseness related to a bearing can also cause excessive runout, which may cause the brakes to pulsate or pull. The most common cause is a warped rotor due to the caliper not retracting. 5. ABS failure, which could be internal or external to the bearing or hub bearing assembly. In extreme cases, internal and external sensors can be damaged from excessive movement caused by too much end-play. This indicates a lack or loss of bearing clamp. This normally results from severe mechanical break up or damage. (Additionally, in designs where the sensor is mounted externally, sensor damage can result from corrosion, stones and other hazards.)
