My Whirlpool washer was making a hideous squeal during various parts of the wash cycle. Between the time I ordered the part and the time I completed the repair, the gear case was seized during a cycle.
I replaced the gear case with the part from AppliancePartsPros.com. It was easy! The repair went smoothly because of the video, which completely explained the process. The washer is now working fine and is quieter than it has been for a few years.
Now if we could just get Whirlpool to make a washer in quality such that I don't have to replace the gear case after only 6 years of moderate use.
