I have a 2015 ford mustang v6 and recently installed new brake pads and drilled slotted rotors. About 2 days after i started hearing a wheel bearing hum while driving on the rear passenger side. Can be heard while off the brakes as a humming noise. While on the brakes it kind of turns into a ticking noise when decelerating. Ive already replaced the wheel bearing hub assembly. Still hearing the noise. Its so annoying. Took it to a shop and they said everything looks and was installed correctly, tires are brand new as well. Any ideas or helpful tips?
