Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to avoid any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel while the vehicle is on the ground.
Use a jack to lift 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 with a socket wrench. Support it with a bungee cord or a brake caliper hanger to avoid stress on the brake line.
Detach the brake rotor by removing the screws or bolts securing it, if applicable.

4. Remove the Hub Assembly

Remove the axle nut using a socket and breaker bar. You may need to use a torque wrench for reinstallation later.
Disconnect any brake line brackets or sensors attached to the hub assembly.
Use a hammer or slide hammer to detach the hub assembly from the steering knuckle. Be cautious not to damage surrounding components.

5. Install New Wheel Bearing

Clean the hub assembly and the steering knuckle area where the new bearing will be installed.
Press the new wheel bearing into the hub using a bearing installer tool or a hydraulic press, ensuring it is seated properly.
Reattach the hub assembly to the steering knuckle and secure it with the axle nut to the manufacturer’s specified torque value.

6. Reassemble Brake Components

Reinstall the brake rotor and secure it with screws or bolts.
Reattach the brake caliper and ensure it is secure.

7. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern to the manufacturer’s torque specifications.

8. Final Checks

Reconnect the negative battery terminal.
Check for any leaks or issues with the brake system.
