How do I know when to replace the drawer slides on a mobile pedestal?

Replace mobile pedestal drawer slides when: drawers stick or require force to open/close even when not overloaded, drawers wobble or list to one side when extended (a sign of worn slide bearings), the drawer falls off the slides when fully extended, or the slides show visible rust or deformation. Ball-bearing slides last longest; undermount and side-mount slides show wear differently. Before replacing slides, try cleaning with compressed air and lubricating with a dry-film lubricant (silicone spray or dry PTFE) — grit and dried lubricant cause more sticking than actual slide failure. Replace both slides simultaneously (left and right) to ensure even operation. FindOfficeFurniture.com — 888-719-4960.
