Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

Use a jack to lift the vehicle and support it securely with jack stands.
Remove the wheel where the bearing is suspected to be bad.

3. Remove the Wheel Hub Assembly

Remove any brake caliper or rotor as necessary (may require a socket set).
Disconnect any brake line or sensor wiring if applicable.
Unbolt the hub assembly from the steering knuckle (torque values may vary; refer to the service manual).

4. Inspect and Replace Bearing

Remove the old wheel bearing from the hub using a bearing puller.
Clean the hub and inspect for any damage.
Install the new wheel bearing by pressing it into place (ensure it is oriented correctly).
Reassemble the hub assembly, ensuring all bolts are torqued to the manufacturer’s specifications.

5. Reassemble Wheel and Test

Reattach the wheel and lower the vehicle.
Reconnect the battery and start the vehicle.
Test drive to ensure that the noise or vibration has been resolved.
