Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and materials.
Disconnect the negative battery terminal to ensure safety.

2. Check Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check fluid level; if low, top it up with the manufacturer-recommended fluid.
Inspect fluid for contamination (dark color, debris). If contaminated, proceed to replace fluid.

3. Inspect for Leaks

Visually inspect power steering hoses and connections for any signs of wear or leaks.
Use a clean cloth to wipe connections and check for wetness.
If leaks are found, replace the affected hoses or fittings.

4. Test Power Steering Pump

Reconnect the battery terminal and start the engine.
With the engine running, turn the steering wheel from lock to lock and listen for unusual noises.
Use a pressure gauge to check the output pressure of the power steering pump. If insufficient, replace the pump.

5. Inspect Serpentine Belt

Visually inspect the serpentine belt for signs of wear, cracks, or fraying.
If the belt is damaged, replace it with a new one, ensuring proper tension is applied according to manufacturer specifications.
