I have been hearing a mild "wobble-chirp" (Best description I can give) when my engine is running, cold or opp. temp. I took a look under the hood to see if it was a belt that was loose but I noticed that the Crank Pulley had a slight wobble to it. I did some research into replacement and found this in the AEM FAQs...

"Why doesn’t AEM make a crank pulley?"

"Virtually all of the cars we make Tru-Power pulleys for come equipped with a vibration dampener mounted to the crank from the factory. Aftermarket crank pulleys require the removal of these dampeners, which are required for engine life. Their removal can cause damage to your engine over time. If the manufacturers could save on vehicle costs by eliminating this device they would have done so."

This leaves me stumped. Any suggestions?
