Product review (5 stars): Completely saved top rack of kitchenaid dishwasher!!
I bought these to replace disintegrating rollers on my kitchenaid dishwasher (purchased in 2013). The top rack kept falling off the track and out of the dishwasher, it would also not push in or out easily. I assumed that I would also need to purchase new rails and other components to the upper assembly - everything seemed wobbly and unable to properly hold up the top rack. NOT SO. Once installed, these new rack rollers stabilized the other parts, and it's been working great ever since. (I found I needed to replace all four rack rollers for this to be the case.) Overall an easy fix - just wish they came in a discounted multi-pack - I'm sure I'll need to replace them again at some point.
