Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, jack stands.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid electrical hazards.

2. Inspect and Tighten Drivetrain Components

Check all bolts and nuts on the drivetrain for proper torque specifications.
Tools Required: Torque wrench.
Sub-steps:
- Refer to the service manual for specific torque values for each component.
- Tighten any loose bolts or fasteners to the specified torque values.

3. Inspect and Replace Worn Components

Check for wear on the drive belt, bearings, and other related components.
Tools Required: Socket set, pry bar.
Sub-steps:
- Remove any covers obstructing access to the components.
- Inspect the drive belt for fraying or cracks; replace if necessary.
- If bearings show signs of wear, replace them with OEM parts.

4. Test Drive

Reconnect the battery and ensure all tools are removed from the engine bay.
Conduct a test drive to assess if the whirring noise persists.
Use various acceleration levels and monitor for any changes in noise.
