Rollers don't fail the same way on a 2002 build as they do on an older one. Across the broader service area, where the median year built sits at 1986, we're often replacing steel rollers that have simply worn through their bearings after decades of use. In Lucas, with most homes built closer to 2002 and 2,724 households in that newer stock, the more common failure is a nylon roller whose factory grease has dried out well before the roller itself wears down - the bearing seizes, the roller flat-spots, and the door starts thumping on one side of the track. The cold-moderate winters here don't help; stiff grease in a sealed bearing resists turning on the first cold start of the day, which is exactly when people notice the noise. It's a different failure mode than the worn-steel-roller problem, and it calls for a different fix - replace the roller with fresh lubrication built in, not just swap steel for steel.
