Removing the driveshaft seal and bearing sleave

[wrndln]

I vaguely remember a technique for easily removing the seal and bearing sleeve from the front of the torque tube. It involved placing a certain size socket, I can't remember what size, on the driveshaft itself and banging the torque tube on the driveshaft with the socket on it. If anyone remembers the technique, please post it.
Thanks
