Solution

1. Preparation

Gather Tools:
- Jack and jack stands
- Lug wrench
- Socket set
- Torque wrench
- Hammer
- Bearing puller (if necessary)
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported by jack stands.

2. Remove the Wheel

Loosen the lug nuts with a lug wrench while the vehicle is still on the ground.
Elevate the vehicle using a jack and secure with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Assembly

Unbolt the brake caliper using the appropriate socket.
Hang the caliper securely (do not let it hang by the brake line).
Remove the brake rotor by unbolting any retaining screws and sliding it off.

4. Remove the Wheel Hub Assembly

Remove any dust cover if present.
Unbolt the wheel hub assembly from the steering knuckle using a socket.
If necessary, use a bearing puller to extract the wheel bearing from the hub.

5. Inspect and Replace the Wheel Bearing

Inspect the bearing for signs of wear, such as roughness or play.
If the bearing is faulty, install a new bearing into the wheel hub.
Ensure correct alignment and press it in evenly to prevent damage.

6. Reassemble Components

Reattach the wheel hub assembly to the steering knuckle and torque bolts to the manufacturer's specifications.
Reinstall the brake rotor and caliper.
Replace the dust cover if applicable.

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and onto the ground.
Torque the lug nuts to the manufacturer's specifications.
