Grinding noises can be caused by several things. The most common are brake pads that are worn to the metal. These will cause a grinding sound as the rotor rotates and rubs against them. The other common cause is bad hub bearings. A bad hub bearing will make a humming/growling noise. Hub bearing noises usually vary in intensity if you turn left or right because of the pressure being put on the bearing. A mechanic, such as one from YourMechanic, can help you determine the cause of the noise and make the appropriate repair.
