Crank Hub: Ticking Time Bomb Article?
I was researching my failed charge pipe and also came across this article. I was wondering how many out there had experience this? I searched the forum and saw nothing obvious. Should I worry? Is it just an attempt on the part of the repair facility to muster business?

Over time with lots of wear and a modified engine this part can fail during high rpm high load driving because it sees more wear than bmw anticipated. It would still take a good over rev to get it to pop. This was really only an issue on a few manual S55 cars (that were over reved) but the internet did its thing and turned it into a huge problem. To my knowledge there's been 1 DCT car that had an actual crank hub failure and it's because it over reved and had a bad trans tune on it. I do not know of an auto N55 having a failure. I don't follow N54 stuff so I am not a good outlet of information but I'd imagine it's similar to S55. I do not want to be a @Riick here but it's not a good idea to replace it if you don't have a failure. It's designed to save your engine for when your being stupid. I'd rather have to replace a crank hub instead of putting a new engine in the car. To answer your "should I worry" question, I'd say absolutely not! Enjoy hitting 7k! Because I am a firm believer in the theory of 'A redline a day keeps the carbon at bay' I redline all of my cars once every time I drive (as long as the oil temp is warm ) While I do not have the most powerful x3 on here mine is FBO and on an E30 map so I'm making good power over stock. If mine never fails yours certainly won't.
