Aged roller carriages
Houses built in that stretch of the 1980s mostly got steel sectional doors on galvanized track with roller carriages sized for the weight at the time, not for forty years of settling foundations and loosened track brackets. An off-track call here usually starts the same way: a bent track flange or a stripped roller hanger, not a torsion spring, which keeps the bill on the lower end of an off-track repair rather than a full hardware swap.
