Wheel Bearing Defect Symptoms

Strange sounds:
Your vehicle may make unusual sounds, such as grinding, rumbling, or roaring, especially when turning. These noises indicate that your wheel bearings may be damaged.

Driving in the presence of damaged wheel bearings exacerbates the problem, leading to further complications and safety risks.

Vibration of the steering wheel:
Feeling steering wheel vibration while driving, especially at high speeds, is a common symptom of poor wheel bearings. This vibration indicates that the wheel bearings are worn out and require immediate attention.

Uneven tire wear:
Regularly inspect your tires for signs of uneven wear. Excessive wear on the inner or outer edge of a tire may indicate a poor wheel bearing. Uneven tire wear can affect traction and handling, posing a safety risk.

ABS Warning Light:
A malfunctioning ABS (anti-lock braking system) warning light on the dashboard may indicate damage to the wheel bearings. A faulty wheel bearing can damage the ABS sensor, triggering a warning light. Ignoring this warning may result in a malfunction of the braking system.

Loose or wobbly wheels:
Loose or wobbly wheels are a clear indicator of poor wheel bearings. You may notice excessive wheel clearance or detect abnormal movement when jacking. Driving with loose wheels is very dangerous and requires immediate attention.

Overheated hubs:
After driving, carefully touch the hub to check for overheating. The excessive heat emitted by the wheel hub indicates friction caused by wear of the wheel bearings. Ignoring an overheated hub can lead to catastrophic wheel failure.

Steering wheel misalignment:
If your steering wheel feels off-center or pulled to one side while driving, it may be due to poor wheel bearings. Steering wheel misalignment indicates damage to the wheel bearings resulting in uneven pressure distribution.

Steering difficulties:
The vehicle's difficulty steering, especially at low speeds, can be attributed to poor wheel bearings. Damaged wheel bearings can hinder smooth rotation of the wheels, making steering challenging and unpredictable.

ABS brakes are prematurely engaged:
Premature engagement of ABS brakes, especially under normal driving conditions, indicates a potential problem with the wheel bearings. A faulty wheel bearing can trigger an error signal to be sent to the ABS system, affecting braking performance.

How to check the wheel bearing for damage

Now that you're familiar with the symptoms, let's dive into how to check for wheel bearing damage:

Visual Inspection:
Visually inspect the wheel bearings for signs of wear or damage. Look for rust, cracks, or excessive play in the hub.

Road Test:
Take your vehicle for a test drive and note any unusual noises or vibrations. Test steering responsiveness and braking performance.

Wheel Motion Test:
Jack up each wheel and check for excessive play or wobble. Spin the wheels by hand to detect any roughness or resistance, which could indicate poor wheel bearings.

Check ABS Sensor:
Check the ABS sensors for any signs of damage or blockage. Clean the sensors and make sure they are properly aligned with the wheel bearings.

Temperature Check:
After driving, carefully touch the wheel hub to check for overheating. Overheated hubs indicate friction caused by poor wheel bearings.

Professional Inspection:
If you are unsure of the condition of your wheel bearings, it is best to consult a professional mechanic for a thorough inspection.
