1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely parked.
Wear safety gloves and eyewear.

2. Check and Top Off Power Steering Fluid

Locate the power steering reservoir under the hood.
Remove the cap and check the fluid level against the dipstick.
If low, add the appropriate type of power steering fluid (consult owner’s manual for specifications).

Visually inspect power steering hoses for cracks or leaks.
Check the power steering pump for any signs of damage or leaks.
If leaks are found, replace the affected hoses or the pump as necessary.

4. Inspect the Drive Belt

Check the condition of the drive belt for fraying or cracking.
Ensure that the belt is properly tensioned.
If the belt is worn or loose, replace it and adjust the tension to manufacturer specifications.

5. Test Drive and Monitor

After completing repairs, take the vehicle for a short test drive.
Listen for any remaining whining noises while making sharp turns.
