Anyone have any input on a harmonic balancer going out on a 2005 Corvette? The car has 70,000 miles and it's sounds like a frequent problem. It seems to me GM should have figured it out long ago how to make a decent product. Are the aftermarket balancers any better and to they have problems with the pickups too and other cars too with the LS engines? I am having a mechanic fix it since it's way over my abilities with the tools I have and no lift.
