Predator claims an early batch of their 2nd generation shafts had ferrule issues. All you need to do is download the form from their website and send it into them. In short order you will have your shaft with a new ferrule on it.
I got one with a ferrule slightly off-center and they fixed it and returned it in no time. As far as those "bad" ferrules, apparently it was an issue early on in production and they fixed it quickly. They claim about 1% had those ferrules.
