Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe working environment.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Ensure the wheel is placed safely aside.

3. Remove the Brake Caliper and Rotor

Remove the brake caliper bolts using a socket set.
Carefully hang the caliper using a wire to avoid stress on the brake line.
Remove the brake rotor by unscrewing any retaining screws or pulling it off if it's stuck.

4. Remove the Hub Assembly

Remove the wheel hub retaining nut using a socket and breaker bar.
Disconnect any ABS sensor wires if applicable.
Use a puller to remove the hub assembly from the spindle if necessary.

5. Install New Wheel Bearing

Press the new wheel bearing into the hub assembly using a bearing press or suitable tool.
Ensure it is seated properly and flush.

6. Reassemble Components

Reinstall the hub assembly onto the spindle and secure with the retaining nut to the specified torque (usually around 100-150 ft-lbs).
Reinstall the brake rotor and caliper, ensuring all bolts are tightened securely.
Reinstall the wheel and lug nuts, tightening in a star pattern to the manufacturer’s specifications.

7. Final Checks

Reconnect the negative battery terminal.
Lower the vehicle and perform a final inspection of the wheel assembly.
