Chances are when you start hearing a loud noise from under the hood of your car as you’re driving, you automatically think it’s an exhaust leak or your car is going to break at any moment. But have you thought about the possibility of a broken — or nearly broken — wheel bearing causing that noise?

Understanding Wheel Bearing Issues

Wheel bearings are essential in the operation of your vehicle. More precisely, a wheel bearing is crucial for the proper function of the hub, tire, and wheel assemblies to work together. The wheel bearing allows friction-free movement and rotation of the hub assembly, and thereby provides smooth tire and wheel rotation. Worn-out or damaged wheel bearings can lead to a range of problems that affect vehicle performance and safety, making it essential for drivers to recognize the signs of trouble.

Signs Your Wheel Bearings Need Attention

When the wheel bearing goes bad, you will notice several symptoms, including:

• Unusual Noises Coming From the Wheels. Listen carefully. The most common and often most-identifiable symptom associated with a bad wheel bearing is noise coming from the wheel or tire area of the moving vehicle. You may mistake this as engine noise, but when you listen closely you will likely hear grinding or grating that gets louder as the vehicle accelerates. Since wheel bearings are not known for wearing out too frequently, the noise is typically suspected to be something else and the problem gets overlooked.
  
  

• Car Feels Loose. Does your car feel loose? When you hear professional drivers talk about a “loose” car, you may not know what that means. It often refers to the steering of the vehicle, which can include wheel bearings. Wheel looseness, or also called wheel play, is another common symptom of a bad wheel bearing. As the bearing begins to wear down, they become loose inside the wheel hub and spindle, which makes your vehicle feel loose while steering.
  
  

• Vehicle Pulling to One Side While Driving. Are you doing the steering, or is the car driving where it wants to? When a wheel bearing corrodes or becomes pitted, the smooth exterior lining is gone and the vibration is transmitted to the tires which may feel like it is “pulling” to one side or the other. As the bearing on one side deteriorates, it puts more pressure on the opposite bearing, leading to uneven wear and increased friction. This uneven wear generates heat, which further accelerates the degradation of the bearing. As a result, the affected wheel may start to wobble or vibrate, robbing the vehicle of its stability and smooth handling, especially when cornering or driving at higher speeds.
  
  

• Tire Wear and Tear. What about your tires? We all know the importance of rotating your tires to promote even wear, but did you know a broken wheel bearing can lead to uneven tire wear too? The looseness of the wheel and the vibration that reverberates through the wheel cause your tires to wear unevenly, meaning you are more likely to have to invest in new tires sooner.

The Impact of Worn-Out Bearings on Vehicle Performance

When wheel bearings wear out, they can have a significant impact on vehicle performance, leading to increased friction and resistance within the wheel assembly. This extra friction forces the engine to work harder to maintain the same speed, resulting in decreased fuel efficiency. Additionally, worn bearings can cause uneven tire wear, as the compromised alignment and stability of the wheels lead to irregular contact with the road surface. Hitting a pothole or other road hazard can exacerbate bearing damage, potentially causing sudden bearing failure and loss of vehicle control. The deterioration of wheel bearings also affects the proper transfer of torque from the engine to the wheels, further compromising handling and increasing braking distance.

FAQs

Q: What is a wheel bearing?

A: A wheel bearing is a crucial component that allows the wheels of a vehicle to spin smoothly by reducing friction.

Q: What are the signs of a bad wheel bearing?

A: Common signs include noise (grinding, humming), vibration, uneven tire wear, and ABS failure.

Q: How often should wheel bearings be inspected?

A: Regular inspections are recommended, especially during routine maintenance and before long trips.

Q: Can I drive with a bad wheel bearing?

A: Driving with a bad wheel bearing is dangerous as it can lead to wheel failure and accidents. It should be addressed immediately.

Q: How long do wheel bearings last?

A: Typically, wheel bearings last between 85,000 to 100,000 miles, but this can vary based on driving conditions and maintenance.

Q: What causes wheel bearings to fail?

A: Common causes include poor maintenance, water and dirt contamination, extreme driving conditions, and manufacturing defects.

Q: Can I replace a wheel bearing myself?

A: While possible, replacing a wheel bearing requires specific tools and expertise. It’s recommended to seek professional help for accurate installation.
