Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, OBD-II scanner, socket set.
Ensure the vehicle is parked on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels for safety.

2. Inspect and Replace Worn Components

Step 1: Wheel Bearings
- Jack up the vehicle and remove the front wheels.
- Inspect the wheel bearings for play or roughness by spinning the hub.
- If faulty, remove the hub assembly and replace the wheel bearings using a bearing puller.
- Reassemble the hub and torque the wheel bolts to manufacturer specifications (typically 80-100 ft-lbs).
Step 2: Serpentine Belt
- Inspect the serpentine belt for fraying, cracking, or signs of wear.
- If damaged, release tension using a serpentine belt tool and remove the old belt.
- Install a new belt following the routing diagram located in the engine bay.
Step 3: Transmission Fluid
- Check the transmission fluid level using the dipstick; if low, add the manufacturer-recommended ATF fluid.
- If the fluid is dark or burnt, drain and replace it, ensuring to replace the transmission filter if applicable.

3. Test Drive

After completing repairs, lower the vehicle, and take it for a test drive to assess if the whirring noise has been resolved.
