Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir.
2. Remove the cap and check fluid level; add new fluid if low (use Ford-approved fluid).
3. If fluid is dirty or contaminated, proceed to flush the system.
4. To flush, siphon out old fluid from the reservoir, then refill with new fluid.
5. Start the engine and turn the steering wheel from lock to lock to circulate the new fluid.

3. Inspect and Replace Power Steering Pump (if necessary)

Sub-steps:
1. Remove any components obstructing access to the power steering pump (such as the air intake duct).
2. Disconnect the power steering lines from the pump (use a line wrench to prevent damage).
3. Unbolt the power steering pump from its mounting bracket.
4. Install the new power steering pump by reversing the removal steps, ensuring to torque bolts to manufacturer specifications (typically 18-25 ft-lbs).
5. Reconnect power steering lines and ensure they are secure and leak-free.

4. Bleed the Power Steering System

Sub-steps:
1. Refill the power steering reservoir with the appropriate fluid.
2. Start the engine and let it idle while turning the steering wheel from lock to lock several times to remove air from the system.
3. Check the fluid level again and top off if necessary.
