Weight of the produce bin with the contents inside had cracked the tracks

First I removed the tracks from each side of the metal rack. Very easy using your hands to slide the tab until the part falls away.

Next I inserted the track into the tab position and snapped it into place.

Warning, dont let your kids pull the produce bin out all the way to the end of the track as it will bend and then finally crack like mine did, but thankfully an easy fix using the PartsSelect.com web site with their easy to navigate parts illustration list and manual.
