Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, stethoscope, torque wrench.
Park the vehicle on a level surface, engage parking brake, and ensure the vehicle is cool.

2. Raise the Vehicle

Use a jack to lift the vehicle and place jack stands securely under the frame.
Remove the wheel using a lug wrench.

3. Remove the Brake Assembly

Remove the caliper bolts using a socket set and hang the caliper securely (do not let it dangle).
Detach the brake rotor by removing any retaining screws.

4. Inspect and Replace Wheel Bearing

Check Bearing Condition: Spin the hub and listen for roughness. If noise or play is present, proceed to replace.
Remove Hub Assembly: Use a socket to remove hub assembly bolts. Use a hub puller if necessary.
Install New Bearing: Place the new wheel bearing into the hub. Ensure proper alignment and use a bearing press if needed.
Reassemble Hub and Brake Components: Reinstall the hub assembly and torque bolts to manufacturer specifications. Reattach the brake rotor and caliper.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

6. Test Drive

Take the vehicle for a test drive to ensure the noise has been eliminated.
