Solution

1. Preparation

Gather tools: socket set, wrench set, fluid level dipsticks, stethoscope, and mechanic's creeper.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Open the hood and locate the serpentine belt.
2. Check for cracks, wear, or fraying; if damaged, remove the belt using a wrench to release tension.

4. Ensure the belt is properly routed according to the diagram on the engine bay.

3. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level using the dipstick or markings on the reservoir.
3. If low, add the manufacturer-recommended power steering fluid until it reaches the appropriate level.
4. Replace the cap securely.

4. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Elevate the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the hub assembly.
3. Check for play in the wheel; if excessive, proceed to replace the bearing.
4. Remove the hub assembly and replace the bearing using a bearing puller.
5. Reassemble the hub and wheel, and lower the vehicle.
