Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery for safety.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the wheel by loosening the lug nuts with a socket wrench.

3. Remove the Brake Components

Sub-step: Remove the brake caliper by unbolting it from the bracket (use torque specifications from the service manual).
Sub-step: Secure the caliper with a bungee cord to avoid strain on the brake line.
Sub-step: Remove the brake rotor by unscrewing any retaining screws and pulling it off the hub.

4. Remove the Wheel Bearing

Sub-step: Remove the hub assembly by unbolting it from the steering knuckle (note torque specifications).
Sub-step: Use a bearing puller to extract the old wheel bearing from the hub assembly.
Sub-step: Clean the hub area thoroughly to remove any debris or old grease.

5. Install New Wheel Bearing

Sub-step: Press the new wheel bearing into the hub assembly using a hydraulic press or bearing installer tool.
Sub-step: Reinstall the hub assembly onto the steering knuckle, ensuring proper alignment.
Sub-step: Torque the bolts to the manufacturer’s specifications.

6. Reassemble Brake Components

Sub-step: Reinstall the brake rotor and secure it with retaining screws.
Sub-step: Attach the brake caliper and tighten the bolts to the recommended torque specifications.

7. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.

8. Final Checks

Reconnect the battery.
Test drive the vehicle to ensure the issue is resolved.
