Front End Vibration

I have an 02 Expedition with a loud front end noise and vibration. I was told that it may be the u joints. I replaced both of the u joints on the front shaft today. It had no effect. Any other ideas?

These truck are famous for warpping front brake rotors. Not sure if thats your problem but you may want to look into it. If your rotors are warpped, look into www.frozenrotors.com and there slotted rotors/pads, you will not warp them and have better braking performance.
