Washer Agitator not working properly

With the help of a You Tube video, which was watched first, then when the parts were delivered, the video was watched again, then we played the video back and paused it after each section was done so we could make sure we were doing the repair correct. The one thing I will mention that the video doesn't mention to do is, before taking the agitator out of the washer, put a mark somewhere on the agitator to tell you which end is the top. Just remember that the top( cap ) will be off, so that will not work. Otherwise it was a good, easy fix
