Solution

1. Preparation

Gather tools: socket set, wrench set, power steering fluid, fluid catch pan.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Power Steering Fluid

Open the hood and locate the power steering fluid reservoir.
Remove the cap and check fluid level; add fluid if low, using the manufacturer's recommended type.
If fluid is dark or contaminated, consider flushing the system.

3. Check for Leaks

Visually inspect all hoses leading to and from the power steering pump for cracks or leaks.
Place a fluid catch pan under the vehicle to catch any drips during inspection.
If any leaks are found, replace the damaged hoses or seals.

4. Inspect Power Steering Pump

Remove the serpentine belt from the power steering pump using a wrench to relieve tension.
Check for any play in the pump shaft and listen for abnormal noises when the pump is rotated by hand.
If the pump is faulty, replace it with a new one, ensuring to properly align and tension the new belt during installation.

5. Inspect Steering Rack

Raise the vehicle safely and remove the front wheels.
Inspect the steering rack for any signs of leakage or damage.
Check tie rod ends for play; replace if excessive movement is detected.
