No it is still spinning the same speed. Having it on the slip yoke in a ladder bar or leaf car I imagine this will happen as they move. I am sure Greg's issue with how it is mounted is the fact that he has a Dana and there is usually not room on the yoke for the collar. I ran mine on the driveshaft tube itself. Some yokes have room back there some don't it seems. I have also removed the magnets and embedded them in the u joint as well.
