Whining/Grinding while driving

[TrailerTrashed]

So it sounds like a little of both from underneath the front of the car; like when some cars go in reverse to give somewhat of a reference.
Neither braking or disengaging to clutch stops it or makes it any less quiet. The only thing it really correlates to is how fast the wheels are turning.
I've changed the tranny fluid and the rear differential just to be on the safe side but it has made no positive difference; in fact the problem seems to be getting louder and more stressful.
Whatever the problem may be, I'm thinking it's beyond my realm of experience, so any information that I can make some sort of diagnosis to either fix myself or take with me to the mechanic so I'm less likely to get raped would be very much appreciated.

God help me if it's the tranny!

How many miles are on the vehicle? What year? A shot from the hip here maybe a wheel bearing on its way out...Especially if its speed dependent...So the faster you go the louder it gets? It doesnt matter if the car is in neutral or not? Say your cruising on the highway at 60 mph and throw the car into neutral do you still hear the noise?

Around 106k, 2003. As far as it getting louder, I'm not really sure. The volume doesn't seem to change when I'm accelerating or slowing down, but the pitch does.
Haven't thrown it into neutral at higher speeds, but have disengaged the clutch with no luck but I'll try it when I get the chance.

yeah I would give that neutral thing a whirl because if the noise does change/disappear than we will have a better idea of where exactly it is coming from... Are there any other drive ability symptoms besides the noise?
