Congrats on getting the pump out!!! Yay
Fabulous Eddie, well first of all your not gonna be able to get the pump housing off without getting that impeller off of the motor shaft first. And directly below the impeller should be the bad seal. Unfortunately it sounds like Jeff said there was a special tool to pull the impeller up and off of the shaft.
Before you do anything I would plug up the drain hose hole and fill the pump with water and see if water still seeps through the rubber spout. Maybe its not coming from under the impeller, but somewhere else (this is highly doubtful).
You are probably going to have to devise some way of getting the impeller off the shaft without GE's special puller.
Any idea's Jeff and everyone else??? You might consider heating the impeller at the bottom of the t-section with a torch and taking a vice grip pliers and locking it under the T, then using a hammer hit the vice grips in an upward fashion to force the hot impeller up.
