After 3 trips to the dealer for non warranty AC repairs in the past month I cut my losses and traded on a new Platnium F-150. Over 3 years I've replaced 2 coil packs, AC compressor, condenser, hoses, and AC module. Seat kept moving and the vibration was still hit or miss. Ford dealers seem to be wheelin and dealin with the new refresh coming later this year. I decided not to wait was the current front looks better IMO. I've never owned a Ford before today and I'm impressed. Wanted to keep my LTZ for many more years, but with 87k miles on my 2014 it was starting to nickle and dime me. VIbration never went away completely even with upgraded Nitto Terra Grapplers. So if you are still having vibration issues checkout the competition as I think you'll be pleasantly surprised.
Best of luck to everyone.
