Agitator Upper section stopped working (did not turn)

After removing the agitator center cap, I removed a single screw. The agitator top section can then be pulled out. The repair kit has instructions on how to replace the old parts. I took longer to do this repair because I washed all the sections and then I realized that you need a little grease which was not mentioned in the previous postings. I used a little lithium grease between the two plastic parts that house the dogs and the bottom section. Once this was done. all that was left was to place the agitator top section, replace the screw (make sure you use the rubber washer supplied in the kit, replace the agitator cap, and you are done. By reading previous postings (some are really very good), and the instructions provided in the Kit, it made this repair an easy task.
