Product review (4 stars): Good Product. Lousy Instructions. Be sure to find a YouTube video.
Great product. LOUSY instructions. Photos small and dark, and the replacement parts, which are much better, are designed differently than the original.parts, so you can't swap them in just by looking at the old part. Thankfully an appliance repair company has a nice video on YouTube to walk you through it. Just type the part number and some keywords in YT's search engine. Tip: Save your "old" wheels from the broken rack, if your dishwasher is a few years old, then the wheels that come with the replacement part will be too big. They don't fit in the pull-out rollers. But the old wheels fit just fine. Easy swap.
