Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as necessary.
Place jack stands securely under the vehicle to ensure stability.

3. Remove Wheel

Using a socket set, loosen and remove the lug nuts from the wheel.
Take off the wheel and set it aside.

4. Remove Brake Components

If necessary, remove the brake caliper by unbolting it and hanging it securely (do not let it dangle from the brake line).
Remove the brake rotor by pulling it straight off the hub.

5. Remove Wheel Hub Assembly

Remove any retaining clips or bolts securing the wheel hub assembly.
Carefully pull the hub assembly off the spindle. If it’s stuck, use a hub puller as needed.

6. Replace Wheel Bearing

Press out the old wheel bearing from the hub assembly using a bearing press tool.
Clean the hub assembly and press in the new wheel bearing until it is seated correctly.

7. Reassemble Components

Reinstall the wheel hub assembly onto the spindle.
Reattach the brake rotor and caliper, ensuring all bolts are torqued to the manufacturer's specifications.
Reinstall the wheel and tighten the lug nuts in a crisscross pattern.

8. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
