The median home in Golden Valley went up around 1966, which puts a lot of these garages on their original torsion hardware - the shaft, the end bearing plates, maybe even the drum - because nobody tears out a working spring system until it breaks. Thing is, torsion springs are rated for cycles, not years, and a spring wound in 1966 has had sixty winters to fatigue. Minnesota's cold band doesn't help: steel contracts in deep cold, torque goes up on a cold morning lift, and that's exactly when an old spring lets go. We also see a lot of original steel track that's slightly bowed from decades of a slightly-off door weight, which throws rollers and wears cables faster than they should. None of this is unique to one street - it's the whole build era. A door with a 2015 opener bolted onto a 1966 spring system is a common combination here, and it means the opener is doing work the spring was supposed to carry, which burns out the motor early.
