why does my Ford F-150 12th Generation (2009-2014) make a hissing noise when I turn

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Wear safety glasses and gloves for protection.

2. Check Power Steering Fluid

• Tools Required: None
• Remove the power steering fluid reservoir cap.
• Check the fluid level; if low, add the recommended type of power steering fluid.
• Inspect the fluid for contamination (dark color or debris).

3. Inspect for Leaks

• Tools Required: Shop towels or rags
• Visually inspect the power steering hoses, pump, and steering rack for any signs of fluid leakage.
• If leaks are found, identify the source for repair.

4. Replace Power Steering Pump (if necessary)

• Tools Required: Socket set, wrench set, pulley puller
• Disconnect the negative battery terminal to prevent electrical shorts.
• Drain the power steering fluid from the pump.
• Remove the serpentine belt from the power steering pump.
• Unbolt the power steering pump from its bracket and remove it.
• Install the new power steering pump and secure it with bolts to the bracket.
• Reattach the serpentine belt.

5. Refill and Bleed the System

• Tools Required: Funnel
• Fill the power steering reservoir with the appropriate fluid.
• Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
• Check fluid levels again and top off if necessary.
