Product review (3 stars): Caution!
Ordered this kit and followed the directions in the video (a link) however by following the directions the bearings weren't seated deep enough and caused the seal to be damaged.  The video instructs you to seat the bearings flush.  Keep in mind the video is not for the Whirlpool model!  I contacted the company and they said I needed to replace the seal... and charged me $30+.  So if you are replacing your bearings and seals.  Search for a better video,  take pictures of your bearings to see how deep they are set in and lastly, the seal they send you is a quality seal however they are a little thinner and may cause leaking if set all the way in (per their Tech).  The bearings are made in Japan and appear to be high quality.
