Fridge is 14 years old. Guides have been broken for at least a couple years and I had repaired them several times. Finally got to the point where I could not glue them back together again. Bought two new guides and installed them. Very easy to do, no tools required. Removed the shelf from the fridge, pushed in the retaining clips and slid the the old guides out. Slid new guides in, reinstalled shelf in fridge and put the drawer back in. Good as new. Ten minute repair (including cleaning the shelf while removed).
