Here is what i've found. Of course you have to move the shaft to stern. I would start lubricating the coupler. Also clean and polish the shaft so the bearing drives off easer. I'm going to run the engine at low rpm, use 600 polishing cloth with a lite oil and let the rotation off the shaft do the work. After you remove the bearing and housing you turn the bearing 90 degrees to the housing and the bearing comes out. On latter models there are set screws that hold the bearing in. I also don't think that the grease zerk does all that great of a job delivering lube.
