I wanna say everything but the super dutys use a EPAS rack (electric-power-assisted-steering). The 5.0 never had the space for a power steering pump. There are aftermarket kits out there to add a pump for hot rod conversions/swaps. I believe the Eco family is the same way, where space for a pump was not part of the plan. The 6.2 and diesel both have provisions for a pump, hence why the Raptor still had hydro steering at the end when every other f150 switched. I think mpg was the biggest push for EPAS. They also have the tuning down pretty well where the effort and road feed back feels real, or at least that's what most people think. Some elect racks are really ****** feeling but Ford has it pretty dialed in.

The super duty still uses the old reliable rugged hydro gear box. Part of that is also because it's still a solid front end.
