i just started getting a vibrating feeling at around 60mph on my 03 fx4 supercrew. from 60 and up the noise gets louder the faster you go(i can feel it in the gas pedal as well).... it almost sounds like a bearing to me... but i cant tell where it could be coming from. i just know its something upfront. i just replaced both universals joints in the rear a few months back with heavy duty ones and i just replaced the front passenger side hub assembly after it went bad...
do any of you guys know what could be causing this rough feeling in the front... like i said, i only feel it when i get to 60mph and faster. from 55mph and below the truck feels totally normal....

definitely sounds like a wheel bearing to me based on the noise getting louder as the truck gets faster.

yeah it could either be a wheel bearing or a broke cv axle up front and also how is the brakes up front?

well, after driving it home yesterday from work i think it is the drivers side hub(wheel bearing)... if i stay on the gas while taking a right hand curve the noise goes away and as soon as i straighten it up it comes back which is exactly what the passenger side was doing but alittle more noticeable though when it went bad... my wife typically drives the truck to work all week except fridays so i dont get much seat time in the truck unless its the weekend but i knew something was up when the noise was worse yesterday then it was the week before and she just looked at me funny when i asked her if she noticed it(go figure)huh.....

off to advance this afternoon i guess.... thanks for the input guys.. hope this fix's it..

I would say change the left ftont wheel bearing and have the driveshaft balancing checked.You should be se, good luck!!
