Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools and materials.
Safety warnings: Allow the engine to cool before working on the power steering system.

2. Inspect Power Steering Fluid Reservoir

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level against the markings on the reservoir.
If the fluid is low, inspect for leaks in the surrounding areas.

3. Check Hoses and Connections

Follow the hoses from the pump to the steering rack.
Inspect each hose for cracks, bulges, or loose connections.
Tighten any loose clamps and replace any damaged hoses.

4. Inspect Steering Rack

Locate the steering rack under the vehicle.
Look for wet spots or fluid accumulation around the seals.
If leaks are found, consider replacing the steering rack or seals as necessary.

5. Inspect Power Steering Pump

Locate the power steering pump, typically near the engine.
Check for any signs of fluid around the pump itself or at the mounting points.
Replace the pump if it shows signs of failure or leakage.
