Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid siphon, funnel, power steering fluid.
Use a siphon to remove old power steering fluid from the reservoir.
Refill with the manufacturer-recommended power steering fluid to the correct level.
Start the engine and turn the steering wheel from lock to lock to purge air.

3. Check and Replace Serpentine Belt

Tools Required: Socket set, torque wrench, belt tensioner tool.
Release tension on the serpentine belt using a belt tensioner tool.
Remove the serpentine belt from the pulleys.
Inspect for wear and replace if necessary with a new belt.
Reinstall the new belt, ensuring it is routed correctly and tensioned appropriately.

4. Inspect Differential Fluid

Tools Required: Socket set, differential fluid, fluid pump.
Remove the differential cover or drain plug (if applicable).
Inspect the fluid for contamination or metal shavings.
If the fluid is dirty or low, drain it and refill with the appropriate differential fluid using a fluid pump.

5. Test Drive

After completing replacements, take the vehicle for a test drive to ensure the whining noise has ceased.
