The frequency is the worst at about 47 mph. It feels like I'm riding on something egg shaped or out of round. I thought tires, but it makes no difference it's the same even after a tire rotation. It also happens at about 65mph but at a lower frequency. That's why I am thinking it's one or both of the rear rotors. I replaced the ujoints and they were good. I forgot to mention I get the vibration at 47mph even when I slow down to turn or stop. It doesn't seem to do it under hard braking.
