Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fluid level dipsticks, flashlight, and safety glasses.
Ensure the vehicle is parked on a level surface, and the engine is off for initial inspections.

2. Inspect and Replace Serpentine Belt

Sub-steps:
- Open the hood and locate the serpentine belt.
- Visually inspect the belt for signs of wear or damage.
- If necessary, loosen the tensioner pulley using a socket wrench to release tension on the belt.
- Remove the old belt and replace it with a new one, ensuring it follows the correct routing.
- Reapply tension to the tensioner pulley and confirm the belt is secure.

3. Check Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir.
- Remove the cap and check the fluid level against the dipstick markings.
- If low, top off with the recommended power steering fluid as specified in the owner's manual.
- Inspect the reservoir and lines for any leaks and repair as necessary.

4. Inspect and Change Transmission Fluid

Sub-steps:
- Locate the transmission dipstick or fluid fill plug.
- Remove the dipstick and check the fluid level and condition (should be red and clear).
- If low or discolored, drain the transmission fluid using a transmission fluid pump.
- Replace with the manufacturer-recommended transmission fluid and check the level again.

5. Inspect Wheel Bearings

Sub-steps:
- Jack up the vehicle and secure it with jack stands.
- Grab each wheel and check for play or grinding noises while spinning.
- If any play is detected, the wheel bearing may need to be replaced.
- Remove the wheel, and follow the service manual to replace the bearing if necessary.
