On an engine harmonic balancer that is wearing out, the rubber can crack or separate, the outer ring can shift out of line with the hub, or the engine can vibrate more than before. With the engine off and cool, look at the rubber and the ring for cracks or movement before you replace it, since vibration can have other sources. The engine takes one balancer, on the crankshaft.
