Rotor runout was the principle cause. All original rotors had their  
as-ground runout etched into the hub area.
All rotors tend to wear true on their spindle, why worn in are better  
than new, especially with UFOs.
I don't believe that UFOs in any way cause or influence CA rubber  
bushing life.  Biased installation is the principle cause.
