SO who was not bein serious? You've never heard the saying "5 will get you 10"? You cannot be serious. You cannot figure it out? 5 will get you 10 = a 50% chance. Come on man. You gotta have more sense than that. Pretty high probability the female drive hex is stripped. You said the drive shaft is good.....or not broken was what you said. Did you look at the end? Is it rounded off? If not, my guess is the oil pump locked up and stripped the female hex out. I have actually seen that a lot lately. I think it's because of cheap imported parts. If everything you pulled out "looks good" as you say, then "the problem" must be down below. 'Taint but one thing left and that's the oil pump.
