如何消除Nintendo Switch Pro手柄上的摇杆漂移

My controller has been having this issue, I've been opening it up and dusting the stick, but that only temporarily fixes this issue. I am considering replacing the stick module, although I am a bit worried that something else is causing drift. Its possible that the shell or upper stick part has worn out or has some sort of opening which is allowing dust and other particles to get into the stick. Any advice?
