Product review (5 stars): Easy to install: Need a T15 torx. Watch Youtube
Finally, a re-engineered replacement for a problem part!  The instructions looked complicated, lots of parts.  I skipped that, and watched the install on youtube, not hard to do.  Need a T15 torx driver bit and a small flathead screwdriver.

I installed 4 to 6 original W10350376 plastic adjusters, bought them in pairs because my family broke so many of them. Finally got to install my
Whirlpool W10712394 Adjuster KIT, this should last MUCH longer!
