Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect Brake Components

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for wear; replace if thickness is below 3mm.
3. Check brake rotors for scoring or damage; replace if necessary.
4. Ensure caliper slides are lubricated and functioning properly.

3. Check Wheel Bearings

Sub-steps:
1. Lift the vehicle securely with a jack and support it with jack stands.
2. Grasp the wheel at the 12 and 6 o'clock positions and wiggle it; any play indicates bad bearings.
3. Remove the hub assembly if bearings need replacement.

4. Examine Drivetrain Components

Sub-steps:
1. Inspect CV joints for torn boots or grease leakage.
2. Check the axles for any visible damage or misalignment.
3. Replace any damaged CV axles or joints as needed.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (typically 76 ft-lbs for Corolla).
2. Lower the vehicle and perform a test drive to confirm the noise is resolved.

Tools Required:
