Solution

1. Preparation

Gather tools and safety equipment: gloves, safety glasses, socket set, jack stands, and a torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect and Replace Drive Belts

Inspect Belts:
- Open the hood and visually inspect the serpentine belt for cracks or wear.
- Check for proper tension; a loose belt can cause whirring noises.
Replace if Necessary:
- If damaged, use a socket set to relieve tension on the belt tensioner and remove the old belt.
- Install the new belt, ensuring it follows the correct routing path. Tighten to manufacturer specifications.

3. Check and Change Transmission Fluid

Fluid Inspection:
- Locate the transmission dipstick and pull it out to inspect fluid level and condition.
- If the fluid is low or dirty, proceed to change it.
Fluid Change:
- Place a drain pan under the transmission and remove the drain plug, allowing fluid to drain completely.
- Replace the drain plug and refill the transmission with the manufacturer-recommended fluid using a funnel.

4. Inspect Wheel Bearings

Visual Inspection:
- Lift the front of the vehicle using a jack and secure it on jack stands.
- Spin the wheels by hand and listen for any grinding or noise.
Replace if Worn:
- If noise is detected, remove the wheel and brake assembly to access the wheel bearing.
- Use a bearing puller to replace the bearing and reassemble all components securely.

5. Final Assembly and Testing

After completing all repairs, reassemble any components removed.
Lower the vehicle and ensure all tools are removed from the engine bay.
