This was a fairly easy fix. The only problem I had was that the cover over the retaining nut was difficult to pull off. I changed to a larger pair of pliers and put a little more muscle to it and it popped right out. There was a little corrosion on the shaft that needed to scraped off for the new agitator to slide on easily but after that was gone the new part slid on and with some downward pressure it seated in.
