The 2015 Ford F550 utilizes a power steering pump to help the steering gears function smoothly, ensuring easier wheel movement. It is important to regularly check the fluid levels to avoid damage to the pump and steering hydraulics. The pump of the F550 is specifically lubricated using Mercon V ATF, as recommended by Ford for its required viscosity. On the driver side of the engine bay, you will find the power steering reservoir, a tall cylindrical plastic container with identifiable symbols on its black cap. If the power steering fluid is low, you may hear whining or high-pitched noises when turning the wheel. It is generally advised to flush most power steering systems every 75,000-100,000 miles.
In 2015, the Ford f550 requires a specific power steering fluid, which is a fully synthetic OE replacement designed for American vehicles.
