Pulled the front driveline out of my 02 Superduty. Ball in the double Cardan joint is toast, making a hell of a racket if it's in 4x4 or if you leave the hubs locked. Pretty sure I'm just going to say screw it and buy a new driveline since they're only $290. I'm stuck with a 2wd in the meantime but we haven't had much of any measurable rain since December so I should be fine.
