Product review (5 stars): Hip, hip hooray!
I spent three weeks searching the internet and numerous phone calls to appliance parts suppliers looking for replacement wheels for my lower dishwasher rack (Kenmore 18" dishwasher model 58714409400 with lower rack part #5304461022) with EVERY SINGLE website and parts dealer telling me that wheels were not available for purchase and that I needed to purchase a completely new dishwasher rack. WRONG! After one failed attempt with a different product, I ordered one of these and what do you know?? It was an EXACT FIT. All of the customer service people I spoke to need to get on the ball and do some more research. You do not need to buy an entire new rack - there are parts (wheels) out there that fit.
