    Harmonic Balancer

    Hello all
    I have had underdrive pulleys put on my 2002 ws6 a few years back. I need to replace the harmonic balancer due to some wobble. I am not sure if that was replaced. I am wondering if I order a street performance replacement if it will be the same ? Any help is welcome , Thank You .

    usually the only pulley replaced for underdrive pulleys is the harmonic balancer

    sure the wobble isn't due to the bolt being loose? Might just need a new bolt.

    Most aftermarket pulley kits will require "keyeing" the crank and replacement pulley as well. Before you bolt the new pulley in, you will have to drill a hole between the crank and pulley to keep the pulley from walking off the crank snout.
