have the steering linkage checked for anything loose. have the wheel balance checked. make sure the tires on the front do not have shifted belts. Roy

from your description, it sounds like you may have got a bad new bearing maybe from a long shelf life or one other thought is the backing plate behind the rotor may be coming in contact with the rotor while moving. Roy

ill look into that i will try one off my friends truck this time. i know theres nothing wrong with his truck. and we have the same truck same year. the sound sounds like it may be coming from front diff. its a shollow feel to the vibration. and i dont feel much in sterring wheel its very very very slite even when the vibrating humming grinding is at its worse. but the feel i get with my feet on the floor is very bad.
