Hello there, vibrations are one of the most common faults with your 2010 F-150. You have done great so far in checking the drive shaft and u-joints as well as replacing the rotors and balancing the wheels. These are all likely causes and ruling those out is crucial. If the problem has persisted after all of these repairs than other common faults would be wheel bearings, transmission mounts, power steering rack, tire rod ends, engine mounts, or a faulty tire. A qualified Technician such as one from YourMechanic will be able to diagnose your vibration and make any repairs required to resolve it.
