Product review (5 stars): Just what I needed!
With my washer falling victim to my constant overstuffing with clothes, these little babies get their teeth worn down and then the agitator won't move...once I tore apart the top of the liquid fabric softener slot, I noticed the area where these were and that the teeth were worn off. Long story short, all it takes is ordering these little things (funny name, too--but they do look like dog ears), taking out one bolt in the agitator, pulling out the area where they sit, replacing them, and putting the bolt back in...Voila! It's like a brand new washer! :0) Glad these can be ordered separately, and that they're cheap--much cheaper than an appliance repair person. :0)
