So ive had this loud grinding noise for a while now but it has gotten worse. Its a Seriously loud grinding noise when my car is in motion or cruising. Ive had people tell me it could be my hub bearing or axle. The grinding comes from my passenger side of the car. Last time i inspected y axles the boot did have a tear in it and was leaking axle grease. So my question is is it my axle because i know my hub bearing cant be making a loud ass grinding like this.
