Most houses in this area, including Hinckley, were built across the 1960s and 70s, and Hinckley's own median year, 1972, sits right in that stretch. Doors from that build era were hung on hardware sized for the steel gauges and spring tensions common then, and a lot of it is still in service decades past its intended life.
Layer the climate on top. This region sits in a cold, severe winter band, and cold is hard on old steel and old grease in a specific way: lubricant stiffens, torsion springs lose a little tension every freeze-thaw cycle, and a bearing that was already worn seizes faster at 10 degrees than it would at 50. A door that's been fine for years can snap a cable on the first hard cold snap of the season, not because anything changed overnight, but because the hardware was already near the end and the cold finished the job.
