Solution

1. Preparation

Tools Required: Jack stands, lug wrench, mechanic’s stethoscope, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues while working.

2. Remove the Wheel

Loosen the lug nuts using a lug wrench while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Wheel Bearing

Inspect: Check the wheel bearing assembly for any visible signs of damage or wear.
Remove: If the bearing is faulty, remove the brake caliper and rotor. Use a suitable socket to remove the wheel bearing retaining bolts.
Replace: Install the new wheel bearing by pressing it into the hub or using a bearing puller/installer kit, ensuring it is seated properly. Torque the retaining bolts to manufacturer specifications.

4. Reassemble Wheel and Components

Reinstall the brake rotor and caliper securely.
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specified value.

5. Final Inspection

Reconnect the battery, start the vehicle, and perform a test drive to ensure the noise has been resolved.
Inspect the area for any leaks or misalignments following the repair.
