Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, torque wrench, OBD-II scanner, multimeter.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to secure the wheels and lift the vehicle with a jack if necessary.

2. Inspect Drivetrain Components

Sub-steps:
- Remove the underbody panel if applicable using a socket set.
- Visually inspect the electric motor for any signs of wear, cracks, or loose connections.
- Check the condition of the transmission fluid (if applicable) for discoloration or debris.

3. Check Wheel Bearings and Axles

Sub-steps:
- Spin each wheel by hand to listen for any grinding or roughness.
- Use a multimeter to check for resistance in the wheel speed sensors.
- If any wheels show signs of abnormal resistance or noise, replace the wheel bearings.

4. Tighten Motor Mounts

Sub-steps:
- Locate the electric motor mounts and inspect for any damage.
- Tighten any loose bolts to the manufacturer’s torque specifications.
- Replace mounts if they are cracked or excessively worn.

5. Test Drive for Verification

After performing the repairs, take the vehicle for a test drive to determine if the noise persists.
