I may beating a dead horse here, but here goes. I bought a 2014 Ford F150 supercrew 5.0l 157" bed. LOVE the truck. SO, I got the truck in Oct 2014 and drove it for about 6 months. I took it back to the dealership for a rear vibration which I suspected to be the tires unbalanced, bad tire, or flat spots. Dealer took tires off and rebalanced them. Still have a vibration at 70-75 mph. The passenger seat headrest shakes forward and backwards. I notice the vibration on every highway trip. In Oct 2015, I took the truck to a local shop , rotated and balanced the tires..... Vibration still there. SO, I schedule and appointment at my local dealership and even take a Tech for a ride to have him experience the vibration. Ford has the truck all day and tells me to pick it up cause," there is nothing wrong with it." I complain and the manager asks me to bring it back another day. Dropped it off a week later and mysteriously the mechanic test drove the truck with a vibration detection device that indicated my truck is "out of spec". He had to rebalance all the tires and reset the two piece driveshaft. I asked about the driveshaft and runout. CRICKETS. Oh, still have the vibration. Has anyone resolved this issue? Should I demand a driveshaft or tire replacement? Does this qualify for a Lemon Law? I'm running out of patience and ideas what to have fixed. Thanks .

Go to a tire shop and have them road force balance them. You can also go to a driveline specialty shop and have them look at your driveshaft, u joints and angles. Under warranty still you have the option of going to other dealerships to have it looked at.

no way would I pay out of pocket....I'd take it somewhere else.

Road force balancing is an option, we do that at our dealership but your local dealer may not have the equipment. I agree with wojo, don't pay for a diagnosis just take it elsewhere.

Like others have said, start with a road force balance. I had a horrible vibration at highway speeds. I had an alignment done and the tires balanced by the dealership and still had the problem. I had discount tire road force balance them and it got rid of the vibration. Dealer wanted $200 to do the road force but since I bought my tires at discount, they did it for free.

Yeah I've got a fairly noticeable vibration at around 80mph and I hope it is something as simple as having a road force balance done.

The 157" wheelbase trucks seem to be prone more to vibration for whatever reason.

There's a ton of information in these two threads. Little bit of a read, but your asking for information. Plenty here.

you're fighting a losing battle. TWO of my F150's had it to the point I couldn't stand it anymore. Balanced tires, Forced balance Tires, new drive shaft. took tires and wheels from another truck.... Still vibrated @ 55mph, and the shake and vibration in the cab was horrible. The bed did a nice little hop looking at it in the rear mirror.


The Tremor didn't have this shake/vibration, but it had the crappy Pirelli Tires.

Its not impossible. I got mine fixed.
