Carl, changing the dogs is a 10 minute job, tops. Pop the cap or softener dispenser off of the agitator. Under there will be a second cap. It'll be a little hard to reach, but has a good handle on it. Pull that one up, too. With a socket and extension, remove the bolt and washer that were hidden by that cap. Reach into the tub, and lift the entire agitator out, lifting by the bottom fins. Hold the bottom part to the floor with your feet and pull the top part off. Turn it upside-down, and the holder and dogs should fall out. Take the old dogs off and put new ones back in their place. While holding the agitator top upside down, carefully guide the assembled pieces back into place and turn the whole thing right-side up and put it back on top of the agitator bottom. The tricky part is carefully guiding the assembled agitator back onto the transmission shaft splines without having the shaft poke your dog assembly back out the top. It took me about 3 tries the first time, just don't hurry. Hold the agitator bottom with your left hand and use your right to hold the top assembly down and guide it onto the shaft. Now you can bolt the top back down. The inner cap will need to have the seal lubricated with shampoo or Dawn to make it snap easily back into the agitator. Don't even try to put that one back on without lubing the seal since you don't want to damage it. Put the cap or dispenser back on and you're done.
