Product review (5 stars): Dishwasher rack revived
At the same time that my drain pump died, the wheels for the top rack died as well. I ordered the replacement wheel system for the top dishwasher rack. This one is metal where it counts.  The old one was plastic. In 15 minutes I had a good-as-new top dishwasher rack. The only advice that I would give is to carefully watch how the rack is disassembled to make assembly easier.
