humming and vibrating

I have a 2010 Ram 1500 Quadcab 4x4 with the 4.7L flex fuel. Recently I have noticed that as I am driving once I get to about 30 mph, I can start to hear a hum coming from under the driver side floorboard. As I increase speed, the hum gets louder and then the truck starts to vibrate. I cant hear it from outside of the truck but definitely on the inside. I think it may be the cv axles but before I replace them, I would like to know if any knowledgeable people would have any advice.
