Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which wheel bearings need inspection.
Secure the vehicle with jack stands to prevent accidental movement.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Inspect the brake components while accessible.

4. Remove the Brake Caliper and Rotor

Unbolt the brake caliper using a socket set and hang it with a bungee cord to avoid stress on the brake line.
Remove the brake rotor by unbolting any retaining screws and sliding it off the hub.

5. Remove the Wheel Hub Assembly

Unbolt the wheel hub assembly from the steering knuckle using the appropriate socket.
If necessary, use a hub puller to detach the hub assembly from the axle.

6. Inspect and Replace the Wheel Bearings

Examine the wheel bearings for signs of wear or damage (pitting, discoloration).
If replacement is needed, remove the old bearings from the hub using a bearing puller.
Install new bearings into the hub, ensuring they are properly seated.

7. Reassemble Components

Reattach the wheel hub assembly to the steering knuckle and torque to manufacturer specifications.
Reinstall the brake rotor and caliper, ensuring all bolts are torqued correctly.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern.

8. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
