Ordered the upper and lower door cams - both live on the hinge at the bottom of the door. Repair took just a few minutes. Four 5/16 machine screws need to be removed and replaced to complete the repair.
My door is slightly different from the one in the video.
One thing that I learned from the video was to prop up the door with a block of wood before starting repair. I don't think I would have thought about that if I hadn't watched the video. For that reason alone, I buy my parts from AppliancePartsPros.com.
