Does it come out at a certain speed? At a certain RPM? Does it run along with the RPM range? When the car is moving or stationary? Did anything happen to the vehicle before it came out (i.e. flood, engine wash, change any part/tires, bad pothole?).

Baka galing sa fuel injector pump.. naranasan ko yan noon though in my case gas engine yun when E10 was introduced. at first humming was low until it gets annoyingly loud/noiticeable! switch back to regular unleaded then nawala kusa...

in addition.. are the wheels aligned? are there signs of uneven wear on the wheels? is the transmission/differential oil at level? wheel bearings perhaps?
