rear end noise... from the front

yea i know it sounds weird... i was on my way home from class last night and i noticed a light vibration in all pedals that ive never felt before and also noticed ive got what sounds like differential gear noise, only its coming from the front of the car... its proportional to vehicle speed, not engine speed, so it gets louder as the car goes faster

i also noticed it seems to go away when i turn left, but gets louder and lower in pitch when i turn right.... wheel bearings are new and freshly packed... my tires are just about up for a rotation, taking turns too fast hehe... im thinkin its just weird tire noise, but wanted a few other opinions, its a low humming noise, not a high whine exactly like gears , and as i said its accompanied by a high-frequency vibration in at least clutch and accel pedal and occasionally the steering wheel as well. im not sure there's much else in the front end that rotates to cause vibration like this... anyone have ideas?

thanks a billion

thanks ill get the tires rotated first to see if that fixes it, if not ill def. check the wheel bearings

lol no way tranny is low, it was just put in and no leaks anywhere, its not the rear end otherwise id definitely hear it from the rear seats with windows up... its coming from under the passenger dash
