Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the wheel where the bearing will be replaced.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully unscrewing the lug nuts and taking the wheel off.

3. Remove the Brake Components

Use a socket set to remove the caliper bolts and detach the brake caliper.
Support the caliper with a bungee cord or similar to avoid tension on the brake line.
Remove the brake rotor by unscrewing any retaining screws or simply pulling it off if not secured.

4. Access the Wheel Bearing

Remove the hub assembly by unscrewing the bolts securing it to the steering knuckle.
Use a hammer and a bearing puller if necessary to extract the wheel bearing from the hub.

5. Install New Wheel Bearing

Clean the hub area and apply grease to the new bearing.
Press the new wheel bearing into the hub assembly using a bearing press tool.
Reattach the hub assembly to the steering knuckle, tightening bolts to manufacturer specifications.

6. Reassemble Brake Components

Reinstall the brake rotor and caliper, ensuring all bolts are secured.
Reattach the wheel and tighten lug nuts to the specified torque setting.

7. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle back to the ground.
