Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, fluid pump, torque wrench, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off before starting any inspections.

2. Inspect and Replace Drive Belts

Sub-steps:
1. Remove any engine covers if necessary for access.
2. Inspect the serpentine belt for cracks, fraying, or signs of wear.
3. If the belt is damaged, remove it using a socket to release tension from the tensioner.
4. Install a new belt, ensuring it is routed correctly according to the belt diagram (usually found on a sticker under the hood).
5. Recheck tension and adjust if necessary.

3. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick, remove it, and check fluid level.
2. If fluid is low, use a fluid pump to add the correct type of transmission fluid (Refer to owner’s manual for specifications).
3. If fluid is dark or smells burnt, consider a full transmission fluid change.
4. Replace the transmission fluid filter if applicable.

4. Inspect and Change Differential Fluid

Sub-steps:
1. Raise the vehicle securely and locate the differential housing.
2. Remove the drain plug and allow the fluid to drain completely.
3. Inspect the fluid for metal shavings or discoloration.
4. Replace with the manufacturer-recommended differential fluid using a fluid pump.
5. Reinstall the drain plug and torque to specifications.

5. Verify and Test Components

Sub-steps:
1. Recheck all fluid levels and ensure no leaks are present.
2. Start the vehicle and listen for the whining noise.
3. Conduct a test drive to ensure noise is eliminated and performance is restored.
