have the problem with there king ranch that when your goin down the highway at about 60 mph or more that the wheel shakes pretty good. Its done this before and the wheels were out of wack, well its not as bad so I think there ok. I have looked in the rims and seen dirt sittin in there but just the back ones would that make it ride rougher. Also when is it time for the first tune up, everyone once in a great while when i step on it there is a small delay, maybe its time for new plugs? thanks.

 

ok so maybe it can be mud in the rims i went through the car wash and blast them out much much better!!!

 

Reminds me of that scene from "My Cousin Vinnie" where Vinnie is told by a good ole' boy that "you got some Mississipi mud in yo tiya"

 

I had the same vibration and took it to the dealer. They said my wheels were out of balance but it came back a few weeks later.

 

go to the car wash blow them out it works

 

The infamous wheel nibble. Your luck if yours is gone. Mine will not go away. Road force balance, rotate tires, different tires, different rims, still there. Dealer says sorry, can't find anything.

 

What size wheels do you have? Are they 20's? If so, you have found your problem. For some reason, F150's don't do well with Plus 3 sizes.

You could do a search on all my posts about it, under RollingRock but brace yourself, you may not like what you find out.

Best of luck to ya.

Had the same problem on my F250. Vibration still there after Road Force balance. Dealer then put it on a lift and ran it at 55MPH, and noticed that the drive shaft was out of round. Replaced under warranty. Vibration gone.

 

Good point, I too had a new drive shaft but that didn't fix my issue on my old F150. Here is a spec you need to know. Ford requires min of 15lbs of Road Force to properly balance....if you have after market they suggest 10lbs of Road Force to balance properly.

Just a little tid bit to pass along.
