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.
