Hail Stephen, King of all Things Technical. Could you please tell me how to remedy a creepy-clunking NP241 slip yoke? I'm assuming you can't just grease it since it's lubed by ATF...soooo if it's worn, how do you prevent the same thing happening again? Oh...and if it is worn, who makes a good complete replacement d-shaft that would be an improvement over stock but not all extra-burly-man that I don't need? Thank you in advance!
