Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Raise Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which wheel bearings are being inspected.
Secure the vehicle on jack stands to ensure stability.

3. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Remove the lug nuts and take off the wheel to expose the brake assembly and hub.

4. Remove Brake Caliper and Rotor

Use a socket set to remove the bolts securing the brake caliper.
Carefully hang the caliper using a bungee cord or similar method to avoid strain on the brake line.
Remove the brake rotor by unbolting it from the hub if necessary.

5. Inspect and Replace Wheel Bearing

Remove the dust cap or retaining ring from the hub if applicable.
Use a socket or bearing puller to remove the wheel bearing from the hub.
Inspect the bearing for signs of wear, such as roughness or excessive play.
Install the new wheel bearing by pressing it into the hub using a bearing press or similar tool.

6. Reassemble Components

Reinstall the brake rotor and torque the bolts to the manufacturer's specifications.
Reattach the brake caliper and torque the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Checks

Carefully lower the vehicle off the jack stands.
Use a torque wrench to tighten the lug nuts to the specified torque value.
Reconnect the negative battery terminal.
