Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in "Park" mode and the parking brake is engaged.
Disconnect the high-voltage battery if working on electrical components.

2. Inspect Drive Unit

Sub-steps:
1. Remove the underbody panels using a socket set (usually 10mm or 12mm).
2. Visually inspect the drive unit for any signs of physical damage or leaks.
3. Check for loose bolts or mounts securing the drive unit.

3. Check Wheel Bearings

Sub-steps:
1. Elevate the vehicle using a jack and secure it on jack stands.
2. Rotate each wheel by hand to listen for grinding or roughness.
3. If noise is detected, proceed to replace the affected wheel bearing.

4. Inspect Accessory Components

Sub-steps:
1. Locate and check the AC compressor, power steering pump, and other auxiliary components.
2. Listen for abnormal noises while the vehicle is on and in "Park."
3. If any component is noisy, replace it as necessary.

5. Reassemble

Sub-steps:
1. Reinstall any removed underbody panels and ensure all fasteners are torqued to specifications (refer to service manual for specifics).
2. Reconnect the battery and ensure all electrical connections are secure.
