If the damper is wobbling it needs to be fixed, it won't necessarily cause internal damage right away but over time the damper will get worse which could lead to premature bearing failure or at worst the damper can completley fail and well ....lets just say the results will be very ugly

I had mine fall off while driving on the highway. Wasn't pretty. In the end there wasnt any internal damage to the engine but it still wasn't pretty. Big pucker factor when it happened. Luckily it happened while still under warranty.

Is it under warranty? If not it'll be like 400 to fix. I had to have mine replaced like 2 times. The second was a part defect. I think it's slowly starting to act up again too. I wonder if it'll be better to get like and ASP pulley?

how do you know if your balancer is wobbling? I was under the car yesterday when it was running, and thought my balancer was wobbling. But after some thought, remembered that the balancer bolt spacer could be a little off center giving the appearance of a wobbling balancer. any input??
by the way I was under the car looking for a power steering leak. i'm hoping it's just the cap, but very hard to determine so far. anyone ever heard of a c5 leaking power steering fluid?

Mine came off at the Runoffs last year and resulted in the loss of the motor. Among the many problems this can cause, there is an oil seal right behind the balancer than the balancer holds in place. Loss of oil pressure at high rpm is not a good thing.
I learned a hard lesson in my case. That lesson being, that if you take the balancer off for any reason, it doesn't stay on very well anymore. I found out after the fact, that most SCCA T1 teams use red locktite on the bolt that holds the balancer in place, though the service manual doesn't call for it. As mentioned above, others have had it pinned.

You use two stainless steel pins in those holes/keyways to keep the balancer from being able to rotate on the crank, which, if allowed to rotate, causes the crank bolt to unscrew, which in turn lets the balancer walk off the end of the crank and tear up expensive stuff...
