why does my Ford F-150 12th Generation (2009-2014) make a whining noise when turning?

Solution

1. Preparation

• Gather tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Place wheel chocks behind the rear wheels for safety.

2. Inspect and Top Off Power Steering Fluid

• Tools Required: Funnel, clean cloth
• Check the power steering fluid reservoir; if low, top off with manufacturer-recommended fluid (typically Mercon ATF for Ford).
• Start the engine and turn the steering wheel from lock to lock to circulate the fluid.

3. Inspect Power Steering Components

• Tools Required: Wrench set, flashlight
• Visually inspect all power steering hoses and connections for leaks or cracks.
• Tighten any loose fittings or replace damaged hoses as necessary.

4. Check the Serpentine Belt

• Tools Required: Belt tensioner tool
• Inspect the serpentine belt for cracks, fraying, or glazing.
• If damaged, replace the serpentine belt ensuring proper tension is maintained.

5. Test Power Steering Pump

• Tools Required: Pressure gauge (optional)
• With the engine running, listen to the pump for any unusual noises indicating wear.
• If the pump is noisy and fluid levels are adequate, consider replacing the power steering pump.

6. Inspect Wheel Bearings and CV Joints

• Tools Required: Jack, jack stands, socket set
• Raise the front of the vehicle and support it with jack stands.
• Spin the front wheels by hand to check for roughness indicating bad wheel bearings.
• Inspect CV joints for any torn boots or grease leaks, replacing if necessary.
