Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, based on which wheel bearings are being serviced.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to remove the wheel lug nuts.
Take off the wheel and set it aside.

4. Remove the Brake Caliper and Rotor

Unbolt the brake caliper using the appropriate socket.
Hang the caliper on the suspension using a bungee cord or rope to avoid straining the brake line.
Remove the brake rotor by unscrewing any retaining screws or pulling it off.

5. Remove the Wheel Hub Assembly

Remove the dust cap from the wheel hub.
Unscrew the retaining nut using a socket and ratchet. Use a breaker bar if necessary for extra leverage.
Pull the wheel hub assembly off the spindle, carefully noting the orientation of any components.

6. Install New Wheel Bearing

Press the new wheel bearing into the wheel hub assembly using a bearing press, ensuring it is seated correctly.
Reinstall the wheel hub assembly onto the spindle and secure with the retaining nut, tightening to the manufacturer's specified torque value (usually between 150-200 ft-lbs).

7. Reassemble Components

Reattach the brake rotor and caliper.
Replace the wheel and tighten lug nuts in a crisscross pattern to the manufacturer's specifications.

8. Lower the Vehicle

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