I would have to guess it is a front wheel bearing. Does it pull to one side? Are your tries good - a bad tire could make a similar noize. It's a wheel bearing. Just replace one on my 2000 Stratus.

If this whining or humming is out of the ordinary, it's probably a bearing or bushing on the belt assembly that's wearing out.
Its most likely a wheel bearing.

A bearing going bad.
I have a similar issue with my Stratus, except instead of humming, mine rumbles slightly. This answer is only speculation, but I believe that it happens because the power steering is stretched to the max while turned completely to the right. You'll hear a humming noise because the hydraulics are trying to pump even more fluid in order to turn further, but there isn't enough fluid in the system. Alternatively, your passenger-side front bearing could be worn out, but it would be much more noticeable than just a humming noise.
