Hi J.R.,
Hard to say for sure. It could be an early sign of worse USM issues to come, or it could be a grain or two of fine sand or something gritty that got in between the focus ring and lens barrel. You should be able to tell if it's grit, because it'll sound a bit crunchy/scratchy. It might get better on its own, and it might not. In any case, it wouldn't hurt to send it in for a cleaning, and ask them to check this particular issue.
