You have a damaged front axle housing! That or your camber adjustments are way off.
I have a 2018 model CTD 4x4 that had this same problem after a few thousand miles. The dealer replaced springs front and rear under warranty but that solved nothing. They eventually found the axle was twisted end to end. After replacing the axle housing all is well.
Easy way to prove this is first check your camber settings. If they are way off, like one side fully CW and the other CCW, then they should first be made the same. Don't worry about the camber angle, you just want to prove if this is causing the lean. When you move the settings from min to max the base of the coil spring will twist and this will raise/lower the body of the truck which is supported by the top of the coil.
I'll answer any other questions anyone has, but trust me the axle housing is twisted.
