Disconnect the 12V battery to prevent any electrical issues while working.

2. Inspect and Tighten Drivetrain Components

Tools Required: Socket set, torque wrench.
Sub-steps:
- Remove the underbody panel to access the electric motor and drivetrain.
- Inspect motor mounts and bolts for tightness; torque them to manufacturer specifications.
- Examine the driveshaft and associated components for any looseness or damage.

3. Check Wheel Bearings

Tools Required: Jack, jack stands, torque wrench.
Sub-steps:
- Lift the vehicle and secure it with jack stands.
- Spin each wheel by hand and listen for any grinding or roughness indicating bad wheel bearings.
- Replace any defective bearings as required, ensuring to torque new ones to specifications.

4. Inspect Electric Motor

Tools Required: Multimeter, torque wrench.
Sub-steps:
- If the noise persists, the electric motor may need inspection. Remove the motor cover.
- Check for any loose connections or signs of wear on the motor assembly.
- Use a multimeter to check the resistance of the motor windings. Replace if out of specification.

5. Reassemble and Test

Reattach all components, ensuring all fasteners are torqued to specifications.
