I have had a snack drawer dropping off the rails for over a year thinking that it was the drawer. My refrigerator is over 10 years old and LG the manufacturer doesn’t do a lot of parts for this model anymore. One morning, tired of the drawer dropping all the time off the track, decided to call appliance parts pros and asked them if they thought it was the drawer itself or the railings? the representative told me that most likely was the railings. I bought them, followed the video and I am a very happy customer to have a functional snack drawer again. It was such an easy modification and I had to suffer it over a year.
