Product review (1 stars): Right part , bad design
Hard to believe Whirlpool approved this design for a high end dishwasher. The part failed after two years . I had to buy two because the other side is beginning to go as well . Whirlpool customer service response was that the parts could fail at any time and they could not be responsible for it after warranty! Now that is a class response for Whirlpool quality.

I note that even low end DWs from other manufacturers have a more sturdy design for this connection. I agree with one reviewer that gluing the wheel to the plate might be the cheapest and equally usable solution. I would suggest using two part plastic epoxy in lieu of super glue.

Next time I will sit on the upper rack at the showroom and see if it holds me!

Amazon has the best price for this.
