Vibrations
This vibration began about a year and a half ago once I switched from Powerslot slotted rotors to some cross drilled rotors with new pads. I switched back to the Powerslot rotors with the same pads I ran them with, but the vibration never went away. The tires & wheels are in good shape, the alignment is perfect. I don’t know what else to replace. I am about replace the spindle sometime this week, but I don’t know if that will fix the vibration. The vibration only comes out when I hit the brakes, be it at 30 mph or 70 mph. As I am driving the car it is smooth. It feels like there is something loose in the suspension, but I have checked all the A- arms bushings and ball joints with a pry bar.
Any help; any suggestion will be appreciated.
