Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, fluid catch pan, and safety goggles.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before inspecting components.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Open the hood and locate the serpentine belt.
2. Use a socket wrench to relieve tension on the belt tensioner and remove the belt.
3. Inspect the belt for cracks or wear; replace if necessary with a new OEM belt.
4. Reinstall the new belt by routing it according to the belt routing diagram.

3. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Remove the cap and check the fluid level; add the recommended power steering fluid if low.
3. If the noise persists, inspect the power steering pump for leaks or failure, and replace if necessary.

4. Inspect and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using jack stands and place a fluid catch pan under the transmission.
2. Remove the transmission pan or drain plug and allow old fluid to fully drain.
3. Inspect the filter; replace it if clogged or dirty.
4. Reinstall the pan, ensuring a proper seal, and fill with the recommended transmission fluid.

5. Inspect Wheel Bearings and Axles

Sub-steps:
1. Raise the vehicle and remove the front or rear wheels as necessary.
2. Check the wheel bearings for play by wiggling the wheel; replace if there is excessive movement.
3. Inspect the axles for any signs of damage or wear; replace if necessary.
