would anyone know the symptoms of a faulty harmonic balancer?

i suspect mine to be bad, but not 100% sure

Harmonic Balancer has no moving parts. It's a weight that hangs off the front end of the crankshaft. I wouldn't thing this is your problem, what are the symptoms. (and model year and engine size and mileage and what you've done so far, etc. etc)
