Sacaton is a small place - about 706 households - which means the fleet of garage doors out here isn't huge, but it's consistent. Most of the housing stock across this service area went up between 1985 and 1993, with a median build year of 1991, and Sacaton tracks that same window. Doors from that era almost always shipped with steel rollers riding in steel track, no nylon, no sealed bearing. After three decades of Arizona heat cycling the track metal, those original rollers wear oval instead of round, and the door starts to shudder instead of glide.
The fix itself is straightforward: we pull the old rollers off the hinges one at a time, working up each side so the door stays supported, and set new 10-ball nylon rollers in their place. On a standard double door that's eight to ten rollers per side. We also check the track for the wear grooves that steel rollers cut into it over the years - sometimes the track needs a light straightening pass, sometimes it's fine. We don't replace track that doesn't need it. If the rollers are original to a 1991-built house, odds are the hinges have some wear too, and we'll flag that rather than just swap rollers and call it done.
