I have a 2006 Harley Ultra Classic with a CSC trike kit on it. I had been noticing a noise in 5th gear and when decelerating and while chasing it down noticed that the half shaft seemed floppy and with further inspection, that it had pulled out of the center section. I can generally figure out things mechanically and just wanted thoughts on what caused this? Is there a clip that holds the half shaft in place or is it just a slip fit?
