Solution

1. Preparation

Tools Required:
- Jack and jack stands
- OBD-II scanner
- Socket set
- Torque wrench
Safety Warnings:
- Ensure the vehicle is on a flat surface and secured with wheel chocks.
- Disconnect the battery if working on electrical components.

2. Check and Top Off Fluids

Sub-steps:
1. Open the hood and locate the engine oil dipstick; remove and wipe clean.
2. Reinsert the dipstick and remove it again to check the oil level. Top off if necessary using the manufacturer-recommended oil.
3. Check the transmission fluid level via the dipstick (if applicable); add fluid if low.
4. Inspect the rear differential fluid level; remove the fill plug and ensure fluid is at the proper level.

3. Inspect and Replace Belts and Pulleys (if necessary)

Sub-steps:
1. Remove the engine cover if necessary to access the serpentine belt.
2. Inspect the belt for cracks, fraying, or other signs of wear. Replace if damaged.
3. Check pulleys for alignment and wear; replace any failing pulleys.
4. Reinstall the serpentine belt, ensuring it is routed correctly per the belt routing diagram.

4. Wheel Bearing Inspection and Replacement (if necessary)

Sub-steps:
1. Elevate the vehicle and secure it with jack stands; remove the front wheels.
2. Rotate the hub by hand; listen for grinding or roughness indicating a bad bearing.
3. If a wheel bearing is faulty, remove the brake caliper and rotor, then remove the hub assembly.
4. Replace the wheel bearing and reassemble components, ensuring proper torque specs are followed.
