After five years of service, and heavier-than-expected use over the past year due to COVID lockdowns (more meals at home & more dirty dishes), two of the wheel assemblies supporting the upper rack of my Maytag dishwasher dried out and cracked. The high heat, water and detergent had taken a heavy toll on the plastic. I did the research and ordered four of these parts to replace all of the OEM assemblies. The new parts are identical to the old ones and installation took less than ten minutes. The only tool required was a screwdriver to pop the plastic gate/latch for each of the old assemblies. Replacement was VERY easy.
