Hi so today while going down ghe highway my Audi i realized had become LOUD and this kinda violent hum that kinda hummed/ vibarted but i more heard it and it came from outside car not the inside any ideas? I have been thinking i have another exhuast leak but ita coming from the front of the car. I thought audi sounded louder earlier in the week but wasnt sure

 

That sounds like a hub bearing to me.
