Post-2000 lighter-gauge track
Most of Raymore's houses went up after 2000, well past the 1951-2005 build window that covers this whole territory, and that later construction changed what fails. Newer builds around here typically used lighter-gauge steel track and rollers designed to be replaced, not repaired, so the common failure is a track that's bent from a car bumper tap or a door that's been forced past a jammed roller until the wheel jumps the rail.
