Yes, the 80w90 is in the list of recommended for the front differential. Here is the recommended list for your truck: https://www.amsoil.com/lookup/auto-and-light-truck/2012/ford/f150-pickup/3-5l-6-cyl-engine-code-t-r-turbo/?volume=us-volume

yeah, 75w140 came with friction modifier in it, but I knew I had ELD device button my 4x4 controller and it's been off all the time plus on 2H. So I knew I'm not suppose to have friction modifier into the rear differential because eld came with limit slip while it's off.
