I had the truck RF Balanced today, and all wheels/tires were within Ford specs. One wheel/tire did need to be re-indexed 180 degrees; 3 were balanced with 1.5 oz. and the 4th was balanced at 1.375 oz.
So, the vibration is now present from about 40 mph and is still very present at 75 mph. I drove a few roads this morning, and went back over them this afternoon, with 4 new (2013) SCab F-150's. The imperfections in the road were present in the 2013 trucks and in my 2011. The one difference I noticed, is the vibration in my steering wheel, floor pan and driver's seat.
What should I check now, the front hubs/bearings? I performed a bounce test on the rear shocks and the rebound appeared normal.

No, not yet. Do you recommend dealer or independent shop? Are the u-joints covered under the 5/60 warranty?
I went back through and read some of the replies. japetras mentioned the possibility of warped rotors. I have noticed the rotors feel slightly warped when braking normally, but no real pull left or right, and it does not occur under hard braking. Also, it doesn't occur evey time I apply the brakes, so I passed it off as sticky brake pads.
Thanks for the help,
James

Maybe the truck just needs the tires to get worn in to fit it, kinda like a new shoe. I'm really interested in why this is happening, but if you have to buy a new truck, again, because of it, I wouldn't be buying a Ford.

I really want to figure this out. After my trip to the dealer and test driving 3 EB trucks and one 5.0L, I don't think I will buy a new F150 anytime in the near future.

Generally speaking, a warped rotor will only show up under braking. If one was really, really warped, it would shake like hell under braking, but I doubt it would shake / vibrate otherwise.
As for where to take the truck to check the driveshaft, if it's under warranty, take it to a dealer you trust. If not, take it to a good independent shop. As for how long universal joints or the dynamic balance of the driveshaft are covered, I think you'd better ask your dealer because I'm not sure.
