I bought my F150 with 8 miles in 2004 and currently have 42653 miles. Recently i've been having issue with the truck vibrating at all speeds thinking its the tire, went to Firestone numerous times for front-end alignment/balance and rotations and still having the same issues. Can't believe with mileage this low that things start happening only 6 years old.Any suggestion?

 

There are some tsbs for driveline issues.

How bad is it? Is it worse at a certain speed?

 

I had some bad vibrations like that in my ranger.......turned out one of the u-joints were bad and the drift shaft was bent. It only had 26,000 miles on it and it was an '05.

 

Yes, when start and stopping, but constant at all speeds even at 100mph.

 

Well, now the ford is going to take a look at it. Hopefully it won't cos.t an arm/leg/lung to repair.

 

If it's a driveshaft, you may want to look for a used one, new one from Ford will be big money.
