OK - - - -we're talking about a different seal. Back where the collar meets the tube there's a round threaded nut that squeezes a cork packing down against the torque tube to seal the lubricant as the tube slides in and out of the ball assembly. That's usually where the leak originates. Apparently you're talking about some type of larger diameter seal between the ball and the back of the transmission?
