What is a wheel bearing?
Your car’s wheels are attached to your car via wheel bearings, which are a main component of the wheel hub assembly. The assembly supports the vehicle’s weight while allowing the tires to rotate freely with minimal friction.
Each wheel has its own steel ball bearings or tapered roller bearings. If one of these bearings goes out, a mechanic will have to disassemble the hub assembly to replace the bearing. Sometimes, the bearing can’t be removed because it’s part of the hub assembly. If this is the case, then you’ll have to replace the whole wheel hub assembly.
How do I know if my wheel bearing is bad?
The most common symptoms of a bad wheel bearing include:
Vehicle pulls to one side: As the bearing fails, you’ll notice the car randomly pull to one side as you drive. This happens randomly.
Steering wheel vibrates: If the wheel bearing is bad, your steering wheel shakes, especially when you accelerate. This can make it hard to steer.
Unusual noises from the wheels: If you hear a grinding noise, clunking, scraping, groaning, or growling sound, it’s a sign that your wheel bearings should be inspected.
Uneven tire wear: If the wheel bearing is bad and it causes the wheel to wobble, you’ll see uneven tire wear on the wheel’s tread.
ABS light comes on: A damaged wheel bearing can trigger the wheel speed sensor to light up even though the anti-lock brake system doesn’t kick on.
Wheel hub movement: Watch the wheel hub as someone drives your vehicle slowly. If you see the hub move up and down or in and out, it’s a sign the bearing is bad.
Loose handling: A worn wheel bearing can make it feel as though you don’t have tight handling or control when driving your car. Schedule an inspection right away if the car feels loose or sloppy when you drive.
How often should a wheel bearing be replaced?
Wheel bearings usually last a long time—between 80,000 and 100,000 miles. If you don’t regularly drive on rough terrain, they could even last up to 150,000 miles. Typically, you only replace a wheel bearing when it starts failing.
Can I replace my wheel bearings myself?
If you’ve got intermediate DIY auto repair skills and want to save on labor costs, you can probably swap out the wheel bearings yourself.
Keep in mind that you will need some specialized tools. If you don’t have a well-stocked garage, you might want to leave it to the professionals.
