Product review (5 stars): (Hopefully) Improved KitchenAid part
Tried this newer replacement for the rack adjusters in my KitchenAid dishwasher. The older version (part # W10350376) has the prongs that hold the wheels on. This newer version has what looks like a solid axle that seems to be unlikely to break as easily as the older version. The body of the adjuster is metal instead of plastic and seems more durable.

Note that the design is different so installing this one requires following the instructions rather than just copying the older one that is already installed. I hope these last a lot longer than the old design. Five stars for now but I'll do a follow-up if they are as short-lived as the older style.

Definitely recommend this newer part over the older one.
