I simply unbolted the 7/16 bolt that's under the fabric softener dispenser and pulled the agitator off the shaft. This time the agitator was so stripped it pulled right off the shaft. I've done this before and at times you really have to work to get the agitator off the shaft. Then I simply snapped off the top auger, lined it up in the slots on the new agitator, pressed the new agitator onto the splined shaft, installed the new bolt and tightened it. I suggest that after a couple of loads you recheck the tightness of the bolt, and then recheck it periodically thereafter. If it loosens too much and you don't catch it, you will strip out the agitator. I did notice that the new bolt supplied by Appliance Parts Pro had Loctite already on the bolt. Great quality parts!
