At highway speeds of 55 to 75 mph and hitting a bump the truck gets the death wobbles & you will have to slow down to about 30 mph to make it stop. Ford won't fix it because I am out of warranty. I have been a ford owner for 35 years my grandfather was a ford dealer that sold model t's & Model a's & all other fords until his death in the 1960's. So I have been a member of a ford family for a long time, he had seven kids & all family left. I am one of the only one's still driving fords. My dad was a salesman for grandpa and is driving a chrysler since 1999. I have had either 9 or 10 new ford trucks, I own a 1929 ford model A that my grandfather sold new, my dad was the 2nd titled owner of that vehicle, with all that bullshit being said I will fix my ford truck & when I trade again ford will not be considered. Will never step foot on another ford dealership lot in my lifetime.
