Product review (5 stars): Very Good OEM Factory Parts Replacement
Very Good OEM Factory Parts Replacement which are original.  Factory directions are less than stellar so I used an excellent online video for the replacement process.  DIY took several hours, which included added time to scrub clean the drain covers covered in soap residue, which eliminated odors too.  Result noticed immediately was quieter operation like new and less vibration, plus no more leaks on the floor.  Requires whirlpool tool sold on Amazon separately better price than retail.  I figure these parts last three years before the leaks, noise, and vibrations manifested.
