Hey guys! need some help.. I recently changed out the front rotors on my 07 dodge charger due to the factory rotors being warped after 48K. There was this humming/warping sound.. its intermittent at this point. It doesnt get louder as the car increases speed. I have 20" rims on my vehicle? could this be the source of the cars noise? I have read in other threads of wheel bearings that have gone bad and/or outer tie end rods. If anyone, can give me any direction it would be greatly appreciated. Thanks!
