Solution

1. Preparation

Tools Required: Socket set, mechanic's stethoscope, OBD-II scanner, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off before starting the work.

2. Inspect and Replace Serpentine Belt

Remove the engine cover if applicable.
Loosen the tensioner pulley using a socket wrench to relieve tension on the serpentine belt.
Carefully remove the serpentine belt from the pulleys.
Inspect the belt for cracks, fraying, or wear. If damaged, replace with a new belt.
Route the new serpentine belt according to the belt routing diagram, ensuring it fits correctly on all pulleys.
Reapply tension using the tensioner pulley and ensure the belt is tight.

3. Address Fluid Issues

If power steering fluid is low, locate the power steering reservoir and fill it with the recommended fluid.
For transmission fluid, locate the dipstick, check the level, and top off if necessary. If low, inspect for leaks and consider a fluid change.
Check engine oil level and top off if low, using the specified oil type.

4. Inspect Wheel Bearings

Lift the vehicle securely using a jack and jack stands.
Spin each wheel to listen for noise and check for any play by pushing and pulling on the wheel at 12 and 6 o'clock.
If a bearing is suspected to be the source of the whining noise, replace as necessary:
- Remove the wheel and brake assembly.
- Remove the hub assembly to access the wheel bearings.
- Replace the bearings with new ones and reassemble.
