Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, flashlight, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is cool before starting.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Release tension on the serpentine belt using a belt tensioner tool.
2. Remove the belt from the pulleys.
3. Inspect the belt for cracks, fraying, or glazing. Replace if damaged.
4. Install the new belt, ensuring it is routed correctly according to the belt routing diagram.
5. Reapply tension to the belt.

3. Check Drivetrain Components

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Inspect the transmission and differential for any signs of leaks or damage.
3. Examine the driveshaft and U-joints for play or wear.
4. If any components are damaged, replace them as necessary.

4. Power Steering Fluid Check

Sub-steps:
1. Locate the power steering reservoir and check the fluid level.
2. If the fluid is low, top it off with the recommended type (usually ATF or specific power steering fluid).
3. Inspect for leaks in the power steering system, including hoses and connections.

5. Test Drive

After repairs, conduct a test drive to assess if the whining noise persists.
