Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, wheel hub puller, bearing grease, and safety glasses.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported before working on it. Disconnect the battery if needed.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Remove Brake Components

Remove the caliper by unbolting it from the bracket (use a torque wrench for proper torque specifications upon reinstallation).
Suspend the caliper using wire to avoid straining the brake line.
Remove the brake rotor by unfastening any retaining screws and sliding it off the hub.

4. Remove Wheel Hub Assembly

If necessary, remove the axle nut using a socket set.
Unbolt the wheel hub assembly from the knuckle (typically several bolts).
Use a wheel hub puller if the hub is stuck on the axle or knuckle.

5. Inspect and Replace Wheel Bearings

Inspect the wheel bearing for any signs of damage or excessive play.
If replacement is necessary, remove the old bearing from the hub assembly.
Press in the new wheel bearing using a bearing press or appropriate tools.
Apply bearing grease as needed.

6. Reassemble Components

Reinstall the wheel hub assembly to the knuckle and secure it with bolts, tightening to the manufacturer's specifications.
Reattach the brake rotor and caliper, ensuring proper torque on bolts.
Reinstall the wheel and hand-tighten lug nuts.

7. Lower Vehicle and Final Checks

Lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
Reconnect the battery if it was disconnected.
