Mysterious Humming Noise

Hey guys, i'm new to all this. I have an '04 E320 and it currently has a weird humming noise coming out of the front area.
I dont want to take it to a repair shop without knowing what the problem is since they will charge like crazy.
I am guessing that it is the bearings although it can be something else.
Does anyone have the same problem or a clue to what it could be?
Thanks

I'm sorry, I was in a rush and should have gone more into detail, the following happens:
It is a humming noise that changes with the speed the car is going at. I have recently noticed that the humming gets more intense as I veer left. It is more noticeable at slow speeds and it makes the car vibrate a bit. The humming starts slow and then blends in with the road noise but it can still be felt in both the steering wheel and the pedals.
The humming is not constant, it sounds something like voom...voom...voom... and the frequency varies with the speed.
