Solution

1. Preparation

Gather Tools: Ensure you have a socket set, jack and jack stands, torque wrench, and OBD-II scanner.
Safety Measures: Disconnect the battery as a precaution before working on electrical components.

2. Tire Inspection and Replacement

Inspect Tires: Check for uneven wear or damage.
Replace Tires: If worn or damaged, replace with OEM or recommended tires. Ensure proper tire pressure is maintained.

3. Wheel Bearing Inspection and Replacement

Remove Wheel: Use a jack to lift the vehicle and secure it on jack stands. Remove the wheel.
Inspect Bearings: Check for any roughness or play in the wheel bearings.
Replace Bearings: If defective, remove the old bearing using a bearing puller and install a new bearing, ensuring proper grease is applied.
Torque Specifications: Torque the wheel bearing nut to the manufacturer's specifications.

4. Electric Motor Examination

Remove Motor Cover: Access the electric motor by removing its cover.
Inspect for Noise Sources: Listen for abnormal noises while the vehicle is stationary. This may require a helper to operate the vehicle while you listen.
Repair or Replace: If the motor is the source of the noise, consult a professional for repair or replacement as it may involve complex electrical components.

5. Drive Axle Inspection and Replacement

Check Drive Axles: Inspect for any visible damage or wear.
Replace Axles: If damaged, remove the axle from the differential and hub, and install a new axle, ensuring proper alignment and securing with torque specifications.
