ok well here is my problem. when driving my car it sounds normal and quiet, but when i get up to 60km/h a loud humming sound comes from the front of the car. it get louder the faster i go. the only time the humming sound stops is if i turn a right corner, but then when i straighten out again the sound comes back. what could it be, and i really hope its not too expensive or too hard to fix, or dangerous to drive with. thanks alot. i appreciate everyones help and oppinions
