Taco 007-F5 circulator noise

The Taco 007-F5 circulator on my boiler has begun making some faint rattling noises over the past several months (it's about 8 years old). The noise is clearly heard when in the same room as boiler. If upstairs is quiet, you can hear the faint rattle following up the pipes. It's definitely coming from the circultator too. If I put my hand on its electrical connection box, I can feel the vibrations in sync with the rattle. It's not loud enough to be annoying; I'm just worried it might be a sign of impending doom. Should I be preemptive and replace it before the cold kicks in?

    If your sure it’s not air, you can either take it apart to see if something is stuck in the impeller, or if there is a flow check in there it could be that failing. Otherwise you probably need a new one. Get a 007e if your sure it was sized properly
