Yea, actually. Gotta pull the tailshaft housing and replace the "cup" (this is all i have ever heard it called). Its purpose is to stop fluid from leaking along the splines and becoming trapped in the bottom of the yoke. (the weep hole is there to let it out so it does not damage anything by being in there) Not sure if you would find this at a parts house, may have to pull a junkyard one.
