Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and safely secured with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level; if low, add fluid per manufacturer specifications (usually ATF or specific power steering fluid).
Inspect fluid condition; if dark or contaminated, it may need to be replaced.

3. Check for Leaks

Visually inspect power steering hoses and connections for any signs of leaks.
Use a clean cloth to wipe areas where leaks are suspected to identify the source.
If leaks are found, mark the locations for repair.

4. Inspect Power Steering Pump

Locate the power steering pump; check the drive belt for wear or looseness.
Start the engine and listen for any unusual whines or noises from the pump.
If necessary, remove the pump for detailed inspection, checking for internal wear or failure.

5. Examine Steering Rack

With the vehicle lifted, check the steering rack for binding or resistance when turning.
Manually turn the steering wheel while observing the rack movement.
If binding is detected, the steering rack may need lubrication or replacement.
