The loud drone sound is from the wheel bearings. I had to replace the two front wheel bearings on my 2004 Mazda3 2.3. try rotating the tires first, because a bad tire will sound almost the same. I also have the same problem. I did rotated my tires but find out all suspensions need to be replace. Bad suspensions cause tires to cupped and make those drone noise.
