On top of the tail housiing, about midway, there is either a small metal plate with two bolts, or a disc type freeze plug.  Remove the plate or plug, and you can see the OD of the bearing and the ends of a snap ring.  With snap ring pliers open the ring into the groove in the case, and tap the shaft out of the housing.
