Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to ensure safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the manufacturer-recommended power steering fluid.
Inspect fluid for contamination or burning smell; if contaminated, a flush may be needed.

3. Inspect Drive Belt

Locate the drive belt and inspect for any cracks, fraying, or signs of wear.
Check the tension of the belt; it should have a slight give when pressed but not be loose.
If damaged or overly worn, replace the drive belt according to the manufacturer's specifications.

4. Examine Power Steering Components

Visually inspect the power steering pump for any leaks or damage.
Check the steering rack and pinion assembly for wear or leaks.
Replace any worn or damaged components as necessary.

5. Test Drive and Adjust

Reconnect the negative battery terminal.
Start the vehicle and turn the steering wheel from lock to lock while stationary to check for noise.
If the noise persists, further inspection of the power steering pump and steering rack may be necessary.
