The upper agitator wouldn't turn and sounded like a stripped gear. I typed into a google search "whirlpool ultimate care II agitator repair" and immediately found AppliancePartsPros.com. Super helpful videos told me exactly what to expect when I disassembled the agitator. On Monday morning I ordered the short cam agitator repair kit, thrust washer, rubber washer for the bolt and an inner cap. The ordered shipped quickly and was delivered by FedEx the next day with a total cost of less than $25. I spent 10 minutes installing the new parts and cleaning up the re-used parts. I couldn't be happier or more impressed with AppliancePartsPros.com.
