Solution

1. Preparation

Tools Required: Socket set, fluid containers, funnel, flashlight
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, top up with the recommended power steering fluid (Honda PSF).
Inspect the fluid for contamination (milky appearance indicates water contamination).

3. Inspect Serpentine Belt

Open the hood and visually inspect the serpentine belt for signs of fraying, cracking, or looseness.
If damaged, remove the belt by relieving tension using a wrench on the tensioner pulley.
Replace it with a new serpentine belt of the correct specification.

4. Transmission Fluid Check

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert it, then remove it again to check the fluid level.
If low, add Honda ATF DW-1 fluid to the appropriate level; if dirty, consider a transmission fluid change.

5. Wheel Bearing Inspection

Jack up the front or rear of the vehicle (depending on where the noise is coming from) and secure it with jack stands.
Grab the wheel at 12 and 6 o'clock and check for play; any movement may indicate bad wheel bearings.
Spin the wheel and listen for grinding or roughness, which indicates bearing failure.

6. Test Drive

After completing repairs, take the vehicle for a test drive to ensure the whining noise has been resolved.
Observe if the noise persists during acceleration and deceleration.
