Product review (5 stars): Whirlpool 8183202 Hinge for Washing Machine - 'Superseded' part number ...
Whirlpool 8183202 Hinge for Washing Machine - 'Superseded' part number seems to have a different tolerance to the hinge pin areas, which on the original was so tight, that after a short period of time would build up corrosion(aluminum and metal don't mix well) and cause the door to bind.  The excessive force needed to close or open the door cause the hinge to actually snap the little connector rod under the hinge.  Definitely worth buying before your hinge actually snaps!
