Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Diagnose Drivetrain Components

Tools Required: Socket set, torque wrench, jack stands, and a mechanic's stethoscope.
Lift the vehicle using a jack and secure it with jack stands.
Inspect the drive axles for signs of wear or damage.
Examine the motor mounts for any signs of excessive wear or cracking.
Use the mechanic's stethoscope to listen to the electric motor and gearbox for abnormal sounds.

3. Check Wheel Bearings and Suspension

Remove the front and rear wheels using a socket set.
Inspect wheel bearings for play or roughness by spinning the hub by hand.
Check suspension components such as control arms and bushings for wear or damage.

4. Inspect Tire Condition and Alignment

Check tire tread depth and inspect for any bulges or irregular wear patterns.
If necessary, perform a wheel alignment to ensure proper tire contact and reduce noise.

5. Reassemble and Test Drive

Reinstall wheels and torque them to the manufacturer’s specifications.
Lower the vehicle and perform a test drive to confirm the noise has been resolved.
