Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Ensure the engine is off and cool before starting work.
Tools required: Jack and jack stands, socket set, torque wrench, fluid pump, and a screwdriver.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Remove the power steering reservoir cap and check fluid level; if low, top off with manufacturer-recommended fluid.
2. If fluid is dirty or discolored, drain the fluid using a fluid pump and replace it.
3. Refill with new power steering fluid, ensuring no air is trapped in the system.

3. Check and Replace Serpentine Belt

Sub-steps:
1. Loosen the tensioner using a socket and remove the serpentine belt.
2. Inspect the belt for cracks, fraying, or glazing.
3. If damaged, replace with a new belt, ensuring proper routing according to the diagram on the engine bay.

4. Inspect and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check the fluid level and condition.
2. If low or dirty, drain the transmission fluid from the pan and replace it with the correct type of transmission fluid.
3. Replace the transmission fluid filter if necessary and refill the transmission with new fluid.

5. Final Assembly

Sub-steps:
1. Reattach the power steering reservoir cap, serpentine belt, and transmission dipstick.
2. Start the engine and let it run for a few minutes; check for leaks in the power steering or transmission areas.
3. Test drive the vehicle to ensure the whining noise has been eliminated.
