Remove upper tray and pull out the bin in the lower drawer. There's a guide shaft gear and rod that goes across, it has to be removed, making sure you don't break the plastic pin that holds the assembly together. Once that is taken out, remove 2 Philips head screws from the inside of the drawer. A clip inside the freezer holds the track in place. Pull out the old, slide in the new, reattach the guide shaft and pin, put bin and top tray back. You're done. It took longer to take the food out of the freezer than it did the repair.
