Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.
Wear safety gloves and goggles.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool
Release tension on the serpentine belt using the tensioner tool.
Remove the belt and inspect for any signs of wear or damage.
If damaged, install a new serpentine belt by routing it according to the belt diagram located in the engine bay.

3. Inspect CV Joints and Axles

Tools Required: Jack and jack stands, socket set
Raise the vehicle securely and remove the front wheels.
Inspect the CV boots for tears; if damaged, replace the CV joint or axle assembly.
Rotate the CV joints by hand to check for smooth movement; replace if rough or binding.

4. Check Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel
Locate the transmission dipstick and pull it out to check fluid level.
If fluid is low, add the appropriate type of transmission fluid as specified in the owner's manual.
If fluid is burnt or discolored, consider a transmission fluid change.

5. Test Drive

After completing repairs, take the vehicle for a test drive to confirm that the whirring noise has been resolved.
Pay attention to any vibrations or noises during acceleration.
