Product review (5 stars): Works for WDT780SAEM2
The most important thing that I wanted to write was that this works for the Whirlpool WDT780SAEM2. I've had it about a year and one of the plastic wheel connectors broke. I looked at multiple repair sites and diagrams before finally purchasing this parts kit. The reason I hesitated is that this new one doesn't really look at all like the old one. Even when I got it, it had no instructions and I scratched my head for a few minutes. As another reviewer pointed out, there is a YouTube video that covers the removal of old and install of new parts. Just look for W10712395 on YouTube. It's an easy install.

I highly recommend this kit if your old rack adjuster breaks. The price is reasonable as well.
