I have read all kinds of post on this forum as well as others about the misterous vibration from these trucks. What I found was something that I have not heard of yet. I went to my local tire store and and asked my buddy to rebalance my tires. He said he wanted to check something first. So, he jacked the rear to the truck up to where the rear tires where not touching. I jumped in and started the truck and put her in gear. He immediatly saw the problem. My right rear tire wobbles left and right somewhere between 1/8-1/4in left and right and up and down. Also you can hear the brake pads hitting the rotors every time the wheel gets to that certain spot. I believe that no amount of balance could correct that amount of movement. I am now certain that the vibration is from a warped axle or rear end housing. I called the dealership they are going to look at it asap. Hope this helps someone else

 

Good catch. Keep us posted.

 

Very interesting. Let us know the outcome.

 

I had a new Good Year tire that wouldn't seat evenly on the rim in my last vehicle--it caused a wobble as well, which in turn caused a vibration at 70mph. Direct Tire found it after 2 visits.

 

I will keep ya'll up to date.

 

Hmmm, subscribing...

 

I go a see the dealer Tues morning. I told them to go ahead and order a right rear axle. They said that have to verify it is the axle. I see their point, but not doubt it is the axle. We will see.

 

Well, I was wrong. It was not the axle like I previously posted. The wobble I was seeing is from the tires. My next question is why would brand new tires be wobblingly. Michelins M/S 2s

They did however change the pinion angle of diffential. I was 2 degrees off. It is now set at 6. This did not change the ride of the truck at all. It is still vibrating.

I test drove two other trucks one with 20's and the other with 18's. They both had the same vibration that I am feeling. The truck with the 20's had a much worse vibration than mine. Another truck that I did not test drive, vibrated also. A tech was working on it at the same time mine was getting worked on.

A customer service rep from Ford not the dealership called me twice yesterday. He told me that since others trucks were have problem then it was "indicative" of these trucks. In other words he was trying to convince me it is normal. I have been some stupid things before, but that took the cake. I guess it is time to lemon law this truck. I have never ownered anything besides fords in my life, and have bleed nothing but blue my whole life. I am sad to say that I am really considering a Tundra or Silverado.

 

Can you give some more details? How many miles on the truck? Original tires? If not, who installed them? Does the vibration get better on long trips? Does the truck sit around any? Have the tires been road forced and matched?

 

So are they going to replace the tire? While you are there, make sure they check the wheel for trueness. I have seen wheels that are out of round, and of course, that makes the tire even more that way. Need to verify that.
If you can have the tire shop take the tire off, and spin the wheel by itself, you can look and see if has some runout. An aluminum wheel should very little if any runout. You can also turn the tire on the rim 180 degrees on the wheel and air it back up. That might make it better.

 

anyone else think there a definite coincidence between things like this and the passenger side tire sticking out almost an inch more than the driver's side on some of these trucks??

 

No, I don't because my tires are not 'perfect' and I don't have any vibrations.

 

They were built that way to hug the friggan road better lol!

 

The roads are so bad up here I can't tell if I have any... my pass side tire does stick out a bit though.

 

I also have a 2010 f150 4x4 with the vibration on decal from 45 -35 kph i work for ford
and so far they don't know what the problem is or if they are going to try fix it.. It's been a long time since i got a new truck and i sure hell won't be happy with this one.
one of our tech have replace just about everything on one customers truck with no
success. my son has the same truck with 18" tires and 3:73 gears no problem yet. I have
20" with 3:55 gears how about you ?????
