Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, and safety glasses.
Safety Warnings: Ensure the vehicle is securely supported on jack stands before working underneath. Wear safety glasses to protect your eyes.

2. Remove the Wheel

Loosen the lug nuts while the vehicle is on the ground.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect the Wheel Bearing

Visually inspect the wheel hub and bearing for any signs of damage or corrosion.
Check for grease leaks or any play in the bearing by moving the hub assembly side to side.

4. Replace the Wheel Bearing (if necessary)

Remove the Brake Caliper: Unbolt the caliper and hang it using a wire to avoid stress on the brake line.
Remove the Brake Rotor: Take off the rotor to access the wheel bearing hub.
Remove the Wheel Hub Assembly: Unbolt the hub assembly from the steering knuckle; use a breaker bar if necessary.
Install the New Bearing: Press the new wheel bearing into the hub assembly using a bearing press. Ensure it is seated properly.
Reassemble: Reinstall the hub assembly, brake rotor, and caliper. Torque all bolts to manufacturer specifications.

5. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified torque value.
