Think of it almost as an infinite polishing machine

so eventually overtime I will have to replace the pulley? Is there a set certain amount of miles that NST recommends to replace it if so? It has been about 25-30 thousand miles since I installed these. I think it is also why my belt is squeaking everytime i start up because it is loose due to friction engraving its place in it lol
