What happens when you use the other hub on the same spindle.
If the rotor in the video a is a brand new rotor...then perhaps it is not the rotor, if the other hub has the same runout on the that same spindle....then maybe it is the spindle that is the issue.??
You will get it right.....just think of all the fun you are having. (sarc)
