Humming Sound

• A faint buzzing sound is the first sign, often confused with an underinflated tire. As the problem worsens, the sound grows louder, potentially reaching the level of engine noise.

Howling and Squealing Sound

• As the bearing deteriorates and loses lubrication, friction increases, causing howling or screeching sounds. These noises become more noticeable as you drive faster.

Clicking Sound

• When the issue progresses, you may hear a faint clicking sound, similar to a small metal ball hitting the wheel. It’s often mistaken for a malfunctioning CV joint but can be a sign of a failing wheel bearing.

Grinding Sound

• This indicates that the wheel bearing is near the end of its life. The grinding sound occurs as the internal components of the bearing fail, sometimes causing the wheel to stop turning entirely. Immediate action is required.

Steering Wheel Vibration

• A faulty wheel bearing can cause vibrations in the steering wheel, especially if the front wheels are affected. If the rear bearings are faulty, the vibration is felt under the seats. Accompanying humming or grinding sounds are a sign to investigate further.

ABS Warning Light on the Dashboard

• If the wheel bearing has significantly deteriorated, it may wobble, causing a fault in the ABS speed sensor, which can trigger the ABS warning light.

Wheel Wobble

• A severely damaged wheel bearing can cause the wheel to wobble. You may notice undesirable play in the wheel when attempting to rotate it from side to side after raising the vehicle.

Vehicle Pulls to One Side

• As the bearing wears down, the vehicle may pull to one side, similar to the symptoms of unbalanced tires or improper tire inflation. This issue worsens if left unchecked.

Steering Wheel Response

• The steering may feel delayed or sluggish if the wheel hub assembly is malfunctioning. This unusual steering response is a sign of wheel bearing failure.
