RE: -=OFFICIAL HPI FIRESTORM THREAD=-
Wow, never heard of that. I'm assuming its the bog bone drive axle your talking about. its not supposed to crack or fall out, especially at the biggest ball part of the axle. Sounds like the machine building the axle shoved the pin in too tight of a hole making it crack. I'd call HPI customer service and get a replacement sent out, From what I understand there very good.
