Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to eliminate any electrical hazards.

2. Remove Wheel and Brake Components

Use a lug wrench to loosen the lug nuts, then lift the vehicle and remove the wheel.
Remove the brake caliper by unscrewing the caliper bolts and securing it with a bungee cord to avoid strain on the brake line.
Take off the brake rotor by removing any retaining screws if present.

3. Remove and Replace Wheel Bearing

Remove the hub assembly from the steering knuckle by unscrewing the hub bolts (use a torque wrench for the correct torque specification).
If necessary, use a bearing puller to remove the old bearing from the hub.
Clean the hub area and install the new wheel bearing, ensuring it is pressed in correctly without damage.
Reinstall the hub assembly and torque the bolts to the manufacturer's specifications.

4. Reassemble Brake Components

Reinstall the brake rotor and secure it with retaining screws if applicable.
Reattach the brake caliper and tighten the caliper bolts to the specified torque.

5. Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the recommended specification in a crisscross pattern.
