A worn engine harmonic balancer can show up as cracks, an outer ring that has shifted on the hub, or vibration from the front of the engine. A worn drive belt, a failing accessory pulley or a loose engine mount can produce similar vibration, so find the cause before buying. Inspect only with the engine off and cool. If the balancer is the cause, this one replaces it.
