Re: Crank pulley wobbling??
I wouldn't worry about a slight wobbling, just visually inspect the unit and make sure the bolt is tightened to factory specifications. Also, the harmonic balancer is a balanced unit and has a mass to help smooth out engine vibrations, that is why it is heavy. I don't think you'd get much benefit from a lighter pully.
