Hi: My name is John H. from Cedar Rapids, Ia. This is my first experience on this forum. My purpose in signing onto the Website is to see if any other 2011/F150 Lariat/Supercrew/6.5' Cargo Box/157" wheelbase units are experiencing what mine is doing. The condition has existed from new (28 miles) to the present 7000 miles on the odometer. I experience what I term a suttle: Vibration, Shudder or Wobble of the drive train when accelerating from a dead stop. The condition is very suttle if the vehicle is empty, (no cargo), but becomes much more pronounced when towing something. In my case, 3600# boat with a tongue wgt of 300 to 350#. The condition will be very short lived, (less than a second) & seems to be in the 1000 to 1500 rpm range from a dead stop. My dealership acknowledges the condition, & believes it to be in the drive train system. I firmly believe that I have never experienced the condition in any other mode other than from a dead stop! Is there anyone else out there? If so, what was the solution? Thanks CRJohn

My '04 (Super Crew short box) has that same issue. Like you say, it is very subtle when the truck is empty but becomes more pronounced when I hook it up to the camper. I always figured it was just a drive shaft balance issue and never really looked in to it.
