Solution

1. Preparation

Gather tools: socket set, torque wrench, fluid containers, mechanic's stethoscope.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect and Replace Serpentine Belt

Check the serpentine belt tension: If it's loose or frayed, it may be causing the noise.
Remove the serpentine belt: Use a socket wrench to relieve tension on the belt tensioner and slide the belt off.
Inspect the belt: Look for cracks, wear, or glazing. Replace if necessary.
Install new belt: Route the new belt correctly around pulleys, ensuring it is seated properly.

3. Check and Replace Power Steering Fluid

Locate the power steering reservoir: Remove the cap and check fluid level.
If low, top off with manufacturer-recommended power steering fluid.
If fluid is dark or contaminated, flush the system and replace with fresh fluid.

4. Inspect and Replace Transmission Fluid

Locate the transmission dipstick: Check fluid level and condition.
If fluid is low or discolored, drain the old fluid and replace it with the manufacturer's specified transmission fluid.
Check for leaks: Inspect seals and gaskets for any signs of leaking fluid.

5. Inspect Wheel Bearings

Raise the vehicle: Use jack stands for safety.
Spin the wheels: Listen for grinding or roughness indicating worn bearings.
Replace bearings if necessary: Remove wheel hub, replace bearings, and reassemble.
