Product review (5 stars): Right Fix for a Flimsy Original Design
My dishwasher top rack failed two times over after several years. The plastic mounts from both right wheels snapped.  A very flimsy design. The repair kit fixes the problem with steel and a huskier wheel mounting. A FAR better solution. Definitely upgrade to this Whirlpool OEM kit. Don't buy the cheaper plastic repair kit. It will take you 30 min max to pull out the hold mountings and install these upgrades.  The instructions are pretty good. And once you have done one side and see how it goes, the second side is less than 5 minutes.
