Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and turn off the engine.
Place wheel chocks behind the rear wheels for safety.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, add the appropriate type of power steering fluid until it reaches the recommended level.

3. Inspect Power Steering Pump and Hoses

Visually inspect the power steering pump for any signs of wear or damage.
Examine hoses for cracks or leaks.
If leaks are found, replace the affected hose or power steering pump.

4. Replace Serpentine Belt (if necessary)

Use a socket set to release tension on the serpentine belt tensioner.
Remove the old belt and replace it with a new one, ensuring it follows the correct routing.
Tighten the tensioner back to specification.

5. Test Drive

Start the engine and turn the steering wheel from lock to lock.
Listen for any residual whining noises and check for proper steering response.
