Product review (5 stars): Kit is great, a much more sturdy build than factory original ...
Kit is great, a much more sturdy build than factory original adjuster system on our Kenmore Elite dishwasher. The old parts were more difficult to take off than installing the new ones! As others have recommended, I agree that the You Tube Whirlpool W10712394 video instructions (13 minute version) make the installation a snap. Start and stop video as you progress through the old removal / new installation process, and you should be back in business in 15 -30 minutes. Adjustment mechanism works great, Wheel axles on new unit seem much more substantial than originals. Our upper rack now works like new again!  Good luck and enjoy.
