Second or third roller set
That matters here because the housing in Brookhaven mostly went up around 1992, and a door that age is usually on its second or third set of rollers already, not its first. What you're noticing is probably one of two things: a grinding or rattling sound as the door travels, worse at the top or bottom of the track where the roller carries the most load, or a door that hesitates and jumps slightly in the track instead of gliding.
