my Ford Explorer makes a whining noise when turning what's wrong

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, fluid catch pan, and flashlight.
• Park the vehicle on a level surface and engage the parking brake.

2. Check Power Steering Fluid

• Locate the power steering fluid reservoir.
• Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
• If low, top off with manufacturer-recommended power steering fluid.

3. Inspect for Leaks

• Use a flashlight to inspect hoses and connections for signs of leakage.
• If a leak is found, replace the damaged hose or seal.

4. Examine the Power Steering Pump

• Disconnect the negative battery terminal to avoid electrical shorts.
• Remove the power steering pump by loosening the mounting bolts using a socket set.
• Inspect the pump for noise or damage; if defective, replace the pump.

5. Inspect the Serpentine Belt

• Check the serpentine belt for cracks, fraying, or signs of wear.
• If the belt is worn, replace it with a new belt, ensuring proper tension is set according to manufacturer specifications.

6. Test Drive and Final Checks

• Reconnect the battery terminal and take the vehicle for a short test drive.
• Monitor for any residual noises while turning and ensure fluid levels are stable.
