When I test drove my 2013 Lariat Super Crew it had a vibration, but having experience with this I told the dealer what was going on before I purchased it and they had the driveshaft sent out to be balanced. Well that was the problem as it rides smooth as hell now. With the 5.0 I get 15.6 mpg in the city in this cold climate with **** GAS!!! Not bad for 4 WD
I knew it had to be driveshaft that was out of balance that was causing all these vibrations in the F150. People waste time with tires/balance and other fixes. Mine was worse in winter as the cold made these shafts even more stiff and out of balanced. Thanks for your input maybe others can use this to go to dealer and get theres pulled and properly balanced.
