We pull the door panels apart at each hinge, replace every roller on the affected run rather than just the one that's obviously bad, and check the track for the flat spots or bends that heavy roller wear tends to leave behind. With 8,652 households in Anthem, this isn't a high-volume grid for us the way parts of Peoria's own service area are - a roller call here is usually one focused trip for one door, not a stop wedged between three others, so we take the time to check the whole run of hinges and brackets while the door's apart rather than just the roller you called about. If you want steel rollers with sealed bearings instead of the nylon stock ones, we install those the same visit - no separate trip for an upgrade.
