Ex mechanic here-- Please get a 2nd opinion. I smell a rat.
PS: I have NEVER heard of body mounts going "bad"!!!!
They actually do. Ford changed the mount material somewhere before 2006, older trucks seem to do better. Good shops that are doing extensive motor work that pull the cabs off usually replace them as part of a PM. Again not all body mount replacements are good, some are really stiff others too soft. Read the reviews!
My 2006 is still pretty good but noticing more vibration through the seat of my pants little by little. Since they have lasted 13 years it wouldn't bother me to replace them with factory units. I do like the ride quality.
