Product review (5 stars): Great replacement part, easy enough for a six year old.
Worked perfectly on my Kenmore Elite 665.13963K015.  This comes with all the parts necessary to replace the old all plastic adjusters and wheels with metal brackets that have screws that hold the wheels securely.  Search YouTube for W10712394 to find an excellent installation video, which includes removing the old adjusters.  It does require a small flathead screwdriver, and a T15  torx hex screwdriver.  My six year old did much of the repair using the YouTube instructions unassisted, and we finished in about 30 minutes.
