front end vibrates at sixty miles mph and above. on 2005 Ford E-250

every movable part was changed including rotors and bearings. could it be something in the steering shaft? feel it in steering wheel only no vibrating in front seats. i spent a lot of money on vehicle can`t give up on it...

Thank you
mr confused.

have your tires rotated to see if that helps
