Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is on a flat surface and turn off the engine.
Disconnect the battery for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the recommended power steering fluid if low.
Inspect the fluid condition; if dirty or contaminated, plan to flush the system.

3. Inspect and Replace Power Steering Belt

Use a socket set to loosen the tensioner bolt and remove the power steering belt.
Inspect the belt for cracks, fraying, or wear.
If damaged, replace it with a new belt, ensuring it is properly tensioned.

4. Check for Leaks

Visually inspect the power steering pump and steering rack for fluid leaks.
Clean any residual fluid with a shop towel and monitor for new leaks after a test drive.
If leaks are found, replace the faulty component (pump or rack) as necessary.

5. Test the Power Steering Pump

Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock while listening for noises.
If the whining persists, replace the power steering pump.
