01What is a car wheel bearing?

  • A car wheel bearing is a crucial component of the wheel hub assembly that enables smooth rotation of the wheel.
  • It consists of a set of steel balls enclosed in a metal ring, which is then installed inside the wheel hub.
  • The wheel bearing allows the wheel to rotate freely with minimal friction and supports the weight of the vehicle.

02Signs of a failing wheel bearing

  • There are several common signs that indicate a failing wheel bearing:
  • Unusual noises: Grinding, humming, or rumbling sounds coming from the wheel area while driving.
  • Excessive vibration: Vibrations felt in the steering wheel or vehicle body.
  • Uneven tire wear: Uneven wear patterns on the tires.
  • Loose or unstable wheel: The wheel feels loose or wobbly when jacked up.
  • If you experience any of these symptoms, it's important to inspect and replace the wheel bearing as soon as possible to prevent further damage and ensure your safety on the road.

03Tools and materials needed

  • Before you start the wheel bearing replacement process, make sure you have the following tools and materials ready:
  • - Jack and jack stands
  • - Lug wrench
  • - Wheel chocks
  • - Socket set
  • - Hammer
  • - Screwdriver
  • - Pliers
  • - New wheel bearing assembly
  • - Wheel bearing grease
  • - Clean rags
  • - Safety goggles and gloves
  • Having these tools and materials on hand will make the process smoother and more efficient.

04Step-by-step guide to changing a car wheel bearing

  • Follow these steps to change a car wheel bearing:
  • Step 1: Prepare the vehicle
  • - Park the car on a level surface and engage the parking brake.
  • - Place wheel chocks behind the rear wheels to prevent the car from rolling.
  • Step 2: Lift the car
  • - Use a jack to lift the car off the ground and place jack stands under the frame for support.
  • - Remove the lug nuts using a lug wrench and take off the wheel.
  • Step 3: Remove the old wheel bearing
  • - Locate the wheel bearing assembly behind the brake rotor.
  • - Remove the brake caliper and rotor to access the bearing.
  • - Use a socket set to remove the bolts holding the bearing in place.
  • - Carefully pull the old bearing out of the wheel hub.
  • Step 4: Install the new wheel bearing
  • - Apply a thin layer of wheel bearing grease to the inner and outer surfaces of the new bearing.
  • - Insert the new bearing into the wheel hub, making sure it is seated properly.
  • - Reinstall the bolts and tighten them to the manufacturer's specifications.
  • Step 5: Reassemble the brake components
  • - Place the rotor back onto the wheel hub and reinstall the brake caliper.
  • - Tighten all the bolts and ensure everything is properly aligned.
  • Step 6: Mount the wheel
  • - Put the wheel back on the wheel hub and hand-tighten the lug nuts.
  • - Lower the car to the ground and use a torque wrench to tighten the lug nuts to the recommended torque.
  • - Double-check the tightness of the lug nuts.
  • Step 7: Test the new wheel bearing
  • - Start the car and take it for a short test drive to ensure the wheel bearing is functioning properly.
  • - Listen for any abnormal noises and pay attention to the handling of the vehicle.
  • Congratulations! You have successfully changed the car wheel bearing.
