Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical issues.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the affected wheel.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Using a lug wrench, remove the lug nuts and take off the wheel.

4. Inspect and Replace the Wheel Bearing

Inspect: Check the wheel bearing visually for any signs of wear or damage.
Remove the Brake Caliper:
- Unbolt the caliper and hang it securely (do not let it dangle on the brake line).
Remove the Rotor:
- If applicable, unbolt and remove the brake rotor.
Remove the Wheel Hub Assembly:
- Unbolt the wheel hub assembly from the knuckle (note torque specifications).
- Carefully detach the old wheel bearing from the hub.
Install New Wheel Bearing:
- Press or tap the new wheel bearing into place using a bearing installer tool.
- Reinstall the wheel hub assembly onto the knuckle and torque to manufacturer specifications.

5. Reassemble the Brake Components

Reattach the brake rotor and caliper.
Ensure all components are secured to the correct torque specifications.

6. Reinstall the Wheel

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

7. Final Inspection

Reconnect the negative battery terminal.
Check for any unusual noises or play in the wheel during a test drive.
