Driving with bad wheel bearings can put you and your passengers’ safety at risk—it can cause your wheel and/or tire assembly to become loose.
To prevent this from happening, make sure that your wheel bearings are in good condition. Watch out for the following symptoms that may indicate a faulty bearing.
What are the Symptoms of a Bad Wheel Bearing?
Here’s a list of the most common bad wheel bearing symptoms:
Growling, Humming, or Rumbling Sounds
Unusual sounds coming from the wheel are often the first sign that something may be wrong with the vehicle’s wheel bearings. Bad wheel bearings produce noises that are often described as growling, humming, or rumbling sounds. In some cases, these failing parts may also produce a high-pitched sound.
It’s easy to overlook this symptom—especially if you often drive with loud music on. But the moment you turn the radio off, these noises become noticeable from behind the wheel.
Wheel bearing noises are typically in sync with the rotation of your tires. The sound may become noticeably louder as your vehicle accelerates. In some cases, the sound may also change depending on the direction of the steering wheel.
Take note, however, that these unusual sounds do not always mean that your bearings are faulty. Cupped tires and other wheel hub-related issues may cause similar noises.
Tire Noise vs. Bearing Noise
If the noises are different across varying road surfaces, there’s a good chance that the sound is being produced by your tires. However, if the sound remains the same, it’s likely caused by failed wheel bearings.
Another way to check the source of the sound is to temporarily overinflate your tires. If the wheels produce the same sound while you drive, the noise is likely coming from your wheel bearings.
Have your vehicle checked by a mechanic as soon as you notice unusual wheel noises. Even if the wheel bearings aren’t the culprit, it’s better to err on the side of caution and make sure that your wheels are in top condition.
Failing wheel bearings can make the steering wheel feel rough and cause excessive vibration when accelerating or cornering.
Play in the Steering
Another symptom that drivers may observe is looseness or excessive play on the steering wheel. This typically becomes more noticeable while driving over rough road surfaces.
Like other symptoms, steering difficulty may be caused by more than one faulty component. It’s best to take your vehicle to an auto repair shop for proper diagnosis.
Uneven Tire Wear
It is normal for tires to wear out because of prolonged use or unfavorable driving conditions. However, uneven tire wear may also be caused by faulty wheel hub components, such as loose bearings that may cause misalignment.
Abnormal tire wear may be caused by other suspension issues, so it is best to let a mechanic rule out other possible parts that may be causing your tires to wear unevenly.
Abnormal Side Pull When Braking
Faulty wheel bearings can cause your vehicle to pull to one side as you apply the brakes. However, take note that it’s also possible to experience abnormal side pull due to faulty brake components as well. For instance, a defective caliper or a worn-out rotor may cause similar issues.
If you’re not equipped with adequate knowledge and tools to identify the problem, let a mechanic troubleshoot your vehicle for you.
Activated ABS Warning Light
Your anti-lock braking system (ABS) warning light may also turn on if you have a bad wheel bearing. This is because the ABS sensor or encoder ring of some vehicles is integrated into the wheel hub assembly.
Whatever the cause may be, vehicle warning lights shouldn’t be ignored. Have your vehicle checked right away, so you can have the wheel bearings or any other faulty components replaced.
What is a Wheel Bearing?
Wheel bearings connect the wheels to the axle, which make them crucial components of the wheel hub assembly. They minimize friction to help the wheels rotate smoothly.
These bearings are usually held together by a metal ring. Most modern vehicles have single wheel hub assemblies, which integrate the hubs and bearings. However, on some vehicles, these two parts are considered two separate components.
The exact structure of your bearing or hub assembly will depend on your vehicle’s year, make, and model.
How Long Do Wheel Bearings Last?
In an ideal scenario, wheel bearings can last up to approximately 85,000 to 100,000 miles. But remember that this is just an estimate. Several factors can affect the lifespan of your bearings, such as their quality and the way you drive your vehicle.
Can I Drive With Faulty Wheel Bearings?
The short answer is no. As mentioned, driving with a bad wheel bearing is dangerous. Severely worn bearings may cause the brake rotors to wobble, resulting in reduced brake performance.
Since the tire assembly may loosen, drivers could end up losing control of the vehicle. Needless to say, this situation could cause major accidents on the road.
In extreme cases, the wheels may even come off completely.
Keep your trips safe and hassle-free by ensuring that all faulty bearings are replaced right away. Have a mechanic check your vehicle as soon as your vehicle exhibits any of the symptoms above. Replace faulty bearings if needed, so you can get back on the road in no time.
