Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Raise the vehicle using a jack and secure with jack stands.

2. Inspect and Replace Transmission Fluid

Tools Required: Socket set, fluid pump, container for old fluid.
Remove the transmission fluid drain plug and allow fluid to drain into a container.
Inspect the fluid for metallic particles or burning smell, which may indicate internal damage.
Replace with new transmission fluid as specified in the owner’s manual (ensure the correct type is used).
Reinstall the drain plug and torque to the manufacturer’s specifications.

3. Check and Replace Power Steering Fluid

Tools Required: Fluid pump, container for old fluid.
Locate the power steering reservoir and remove the cap.
If the fluid is low, fill it with the recommended power steering fluid.
If the fluid is dark or contaminated, perform a complete fluid change.

4. Inspect and Replace Wheel Bearings (if needed)

Tools Required: Socket set, torque wrench, bearing puller (if applicable).
Remove the wheel and brake assembly to access the wheel bearings.
Check for any play or noise in the bearings by spinning them by hand.
If damaged, replace the bearings with new ones, ensuring proper installation and torque.

5. Reassemble and Test

Reinstall all components removed during inspection.
Lower the vehicle and take it for a test drive to confirm the whining noise has been resolved.
