Solution

1. Preparation

Gather necessary tools and parts before beginning the repair.
Tools Required: Jack and jack stands, socket set, torque wrench, wheel chocks, screwdriver set, bearing puller (if necessary).
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported before working underneath.

2. Remove Wheel

Loosen the lug nuts with a socket wrench before lifting the vehicle.
Use a jack to raise the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unbolting it from the bracket. Suspend it using a bungee cord to avoid stressing the brake line.
Take off the brake rotor by removing any retaining screws or bolts.

4. Inspect and Replace Wheel Bearing

Inspect the wheel bearing for signs of damage or excessive play.
Use a bearing puller to remove the old wheel bearing if it needs replacement.
Install the new wheel bearing by pressing it into the hub assembly, ensuring it is seated properly.

5. Reassemble Components

Reinstall the brake rotor and ensure it is secured with retaining screws or bolts.
Reattach the brake caliper and tighten the bolts to the manufacturer's specified torque.
Place the wheel back onto the hub and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Carefully lower the vehicle back to the ground.
Tighten the lug nuts to the manufacturer's specified torque in a crisscross pattern.
