5 of the 8 wheels on the lower dishwasher rack had broken off

I simply snapped the new wheel assemblies back on. The main thing I want to say is that I have never owned a dishwasher that required replacing wheels and I believe there is a design flaw in the wheel that they break so easily. If you look at the way they are mounted on the rack, eventually the weight of dishes on the rack will wear them out and break them. It cost me nearly $50 to replace them all. I bought extras because I know more will break in the future.
