Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety.

2. Inspect and Top Off Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level; add the manufacturer-recommended power steering fluid if low.
Inspect fluid condition; if dirty or contaminated, it needs to be flushed.

Visually inspect the power steering pump and hoses for any signs of fluid leaks.
Clean any spilled fluid and run the engine, then re-inspect for new leaks.

4. Test Pump Functionality

Start the engine and turn the steering wheel fully to the left and then to the right.
Listen for whining or grinding noises indicating pump failure.
If noise persists, proceed to pump replacement.
