Product review (5 stars): Replacement for original part--so far so good after several months. March update--still working as designed. Glue holding.
Replaced broken original with this product, after gluing wheel axles as recommended in some reviews. So far have gone several months and all working well. We will see what happens over the next 12-18 months, the usual failure time for the factory part. Follow YouTube videos for assistance in installing. Be careful not to snap the plastic.

One wonders why KitchenAid doesn't build a more reliable assembly, since this is a known design flaw.
