Product review (1 stars): A waste of money.
This replacement part is cheap plastic just like the original.  It failed within a week of installation.  I broke down and called for a Sears repairman to come out.  He replaced the part (both sides) with a stainless steel part; it's been a couple of months now (with nearly daily use) and the new part is going strong.  The repairman said that he has replaced "dozens" of these and has never had to replace the metal ones.  The original part should have been made of stainless steel.
