2007 Ford F-150 front end

I have a intermittent humming with a slight vibration in the front end of my 07 f150 lariate.My question is would bad iwe cause the vibration as well as a humming and would it still do it with the front driveshaft removed?with driveshaft out noise and humming completely gone.I have already replaced both wheel bearings and had tires rotated and balanced,thought that might be the problem.....silly me.... too easy lol
