I am in need of some suggestions please. I have a 2000 Ford F350 4wd crew cab, short box, 7.3 diesel. I am trying to chase down an annoying vibration that I can feel in the steering wheel and also can be felt through the center console if I put my hand on it, and also through the gas pedal. Here's what I have done so far....New Moog upper & lower ball joints, new inner and outer tie rods, new shocks, new rotors, new pads, new calipers, & new steering stabilizer. Oh and also replaced all sway bar bushings, the hubs were bad so right now I am running without any hubs in it till I get new Warns. Of course had a front end alignment, and all new tires. So here is what I have figured so far...The vibration is slight and I believe I ruled out the drivetrain, I drove up a very steep hill and coasted down in neutral....vibration still present. Oh just so I can be as accurate as possible I also replaced the pinion seal and all 3 U-joints. Any input would be much appreciated.

Respectfully,
Nick
