Is it normal for wheel hubs to wobble, even a tiny little Or are they supposed to be true and flat 90 to the axel? The video you're about to watch is with a rotor on the wheel hub assembly. A brand new rotor was installed and the same thing happened but that part is not in the video. So I want to be clear there is no problems or warpage with this rotor, it is perfectly shaped the way it's supposed to be.
