I purchased a replacement wheel and bracket from Appliance Parts Pros.com. I watched the video on the website on how to replace the part and followed that. However our dishwasher is 20 years old and the endcaps that needed to be removed to remove the rack from the dishwasher are quite different, and less user-friendly, to those in the video, so I took me a while to figure out how to gently remove the endcaps without breaking them. That probably added about 10 minutes to the process compared to the video.
