Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and allow it to cool if previously driven.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the wheel covers or hubcaps if applicable.

3. Remove the Wheel

Use a socket set to loosen and remove the lug nuts.
Carefully take off the wheel to access the brake assembly and hub.

4. Inspect the Wheel Bearing

Visually inspect the wheel bearing for signs of damage or wear.
Check for excessive play by moving the hub back and forth.

5. Replace the Wheel Bearing (if necessary)

Remove Brake Components: Remove the brake caliper and rotor to access the wheel hub.
Disconnect the Hub: Remove the hub assembly bolts, using a torque wrench to note torque specifications for reinstallation.
Install New Bearing: Install the new wheel bearing by pressing it into place or replacing the entire hub assembly.
Reassemble: Reinstall the hub, brake rotor, and caliper. Ensure all fasteners are torqued to specifications.

6. Reinstall the Wheel

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

7. Final Check

Ensure that all components are secured and check for any signs of leaks or issues before test driving.
