2. Inspect and Replace Serpentine Belt (if worn)

Tools Required: Socket set, belt tensioner tool.
Sub-steps:
1. Locate the serpentine belt tensioner and use the tensioner tool to relieve tension.
2. Remove the serpentine belt from the pulleys.
3. Inspect the belt for any signs of wear or damage.
4. Replace with a new serpentine belt if necessary, ensuring it is properly routed around all pulleys.

3. Check and Top Off Fluids

Tools Required: Funnel, fluid containers.
Sub-steps:
1. Check transmission fluid level using the dipstick, and add fluid if low.
2. Inspect power steering fluid and add as needed.
3. Check differential fluid levels and replace if necessary.

4. Inspect and Replace Wheel Bearings (if faulty)

Tools Required: Jack and jack stands, socket set, wheel bearing puller.
Sub-steps:
