Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, and a pry bar.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.

2. Raise and Secure the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench and socket set.

3. Remove the Brake Components

Remove the brake caliper and bracket using the appropriate socket.
Hang the caliper securely (do not let it dangle on the brake line) using a bungee cord or rope.
Remove the brake rotor by sliding it off the hub.

4. Inspect and Replace the Wheel Bearing

Check for Damage: Inspect the wheel bearing for any visible signs of wear or damage.
Remove the Hub Assembly: If the bearing is damaged, use a socket set to remove the hub assembly from the knuckle.
Replace the Bearing: Press the old bearing out of the hub using a bearing puller and press the new bearing into place, ensuring it is properly aligned.

5. Reassemble Components

Reattach the hub assembly to the knuckle and torque the bolts to the manufacturer's specifications.
Reinstall the brake rotor, caliper, and bracket, ensuring all components are securely fastened.
Reattach the wheel and tighten the lug nuts in a crisscross pattern to the specified torque.

6. Lower the Vehicle

Carefully lower the vehicle and reconnect the negative battery terminal.
