Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the 12V battery to ensure safety.

2. Inspect Electric Motor

Remove the access panel to the electric motor.
Check for any debris or obstructions near the motor.
Inspect the motor bearings for excessive play or damage.
If worn, replace the motor bearings.

3. Check Wheel Bearings

Lift the vehicle using a jack and secure it with jack stands.
Spin each wheel by hand and listen for any grinding or unusual sounds.
If a wheel bearing is found to be faulty, remove the wheel and replace the bearing using a bearing puller.

4. Examine Drive Belt and Pulleys

Inspect the drive belt for signs of wear or fraying.
Check pulley alignment and condition for any signs of damage.
If the belt is damaged, replace it with a new one, ensuring the correct tension is applied.

5. Reassemble and Test

Reinstall any components that were removed during the inspection.
Reconnect the battery.
Start the vehicle and test drive to determine if the noise persists.
