Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the car is still on the ground.
Lift the vehicle with a jack 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 mounting bracket (usually two bolts).
Secure the caliper to the suspension using a wire or bungee cord to avoid straining the brake line.
Remove the brake rotor by pulling it off the hub.

4. Remove the Hub Assembly

Remove any dust caps or retaining clips that may be present on the hub.
Unbolt the wheel bearing from the hub assembly using a socket and ratchet.
If necessary, use a puller to remove the hub assembly from the wheel bearing.

5. Install New Wheel Bearing

Clean the mounting area on the hub where the new bearing will be installed.
Press or tap the new wheel bearing into the hub assembly, ensuring it is seated properly.
Reinstall the hub assembly onto the vehicle, securing it with bolts and tightening them to the manufacturer's specified torque.

6. Reassemble Brake Components

Reinstall the brake rotor and secure it in place.
Reattach the brake caliper and tighten the mounting bolts to specification.
Replace any dust caps or retaining clips that were removed.

7. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the specified torque value in a crisscross pattern.
