Our mirrored sliding doors used to come out of the bottom track. It was easy to replace the plastic slider in the track once I figured out how. The cause was, the factory had the sliding plastic guide adjusted too tight. We are going to replace one of them because the "silver" backing came off the glass, leaving some black spots in the mirror. I called a glass shop and they said just bring the door in for mirror replacement.
