Dog ears worn down; upper agitator not moving

Pulled off the dispenser. Used socket set to remove bolt. Removed entire agitator out of washer. Placed both feet on bottom of agitator and then pulled up on the upper agitator. It took some muscle due to the years of washer use. I used a flat-head screwdriver to weaken the plastic clips holding down the old bearing-driven cam. Once I got the upper agitator off, the guts were easy to pull out. Then I just re-assembled with the 3 new parts (the Cam Driven, the Dog Ears, and the Bearing-Driven Cam).
