Had my Harmonic balancer replaced 5 month ago. Last week heard loud chirping come from engine and now harmonic balancer is wobbly again. New bolt was put in. Oem balancer. Could it have failed that fast. When the engine is on I can see the bolt turns true and rubber seems ok

It could have.
How certain are you that 1) the chirping is coming from the balancer, 2) the old balancer was bad, and 3) the old balancer was actually replaced?
There was a fellow on here recently who paid for a balancer replacement but got a fresh coat of black spray paint instead.
Never replace a failed harmonic balancer with a new OEM harmonic balancer
Stay as far away from the stock OEM balancers as you can ...
Why do people grab their pitch forks and blindly follow the crowd on this. I had a new OEM balancer installed on my 2006 base a year and a half ago under my used car warranty. My OEM balancer is still fine today. My factory balancer lasted 13 years and 45,000 miles. I expect the same with this one.

The OEM balancer does seem to have a high failure rate and not just on C6's but on pretty much any LS engine.
While I am sure that there are millions of OEM balancers that are fine, the amount of work you have to do to replace one on the C6 means that I would only want to do it once. So go with a higher quality balancer that has a much lower failure rate.

Remember the Firestone tire controversy where the tread would separate and it caused over 250 fatalities? Replacing an OEM balancer that's known to fail with another one is just like buying another set of firestones after you nearly wrecked from your last set that's known to have issues. I'm sure thousands of people were unaffected by those tires but why risk it? I was affected by the balancer issue and I would have to have the IQ of 50 to think about replacing it with another OEM part.

Let's not forget whose thread you're replying to. Somebody whose OEM crank pulley failed (again) after only 5 months.
I think your own example, anecdotal though it may be, is more evidence for the prosecution. One failed crank pulley in 45K miles isn't a ringing endorsement, and a new one that's still going after 18 months isn't much of an accomplishment. Most cars' crank pulleys last forever.
I've had better luck than either one of you, and I'm with the crowd on this. My car made it twice as far as yours did before I decided to change the pulley because it was wobbling. The new one wobbled too, but not as much.
New C6s on dealer lots had wobbling pulleys. Most of them never got too bad. But enough of them did, and the repair is so labor-intensive, that I understand the urge to find a better alternative.

Ok, we will have to agree to disagree. I see an HB as a consumable part. It will sacrifice itself by absorbing the vibrations of the crank. Over time, it will fail. It has a shelf life. My 45k miles and 13 years is acceptable to me. ( 5 months of course not). And my OEM HB install, 2 s-belts, and 4 wheel alignment was free to me thanks to the warranty. I've always been an advocat of using OEM factory parts. But if this is a weak part, I would love to see some analytics re the number of parts out there and the percentage of fails vs passes. Peace out.
Well. I have a 2011 GS that I purchased new. The car has only 19,000 miles on it.
No wobble of the stock balancer, but, in my case, I needed to pin the balancer prior to installing the supercharger awhile ago.
Since pinning the balancer involves just about all the work that replacing the balancer with a new one does, it would have been crazy for me to pin that non-wobbling OEM balancer.
Of course, I ****-canned the stock balancer and replaced it with a 'PowerBond Race Performance' balancer (P/N: PB1117SS) ... and then pinned that.
Had I just pinned the OEM stock balancer, it would have been my luck that it would start wobbling after a short period of time.
Bottom line .... I am very glad I got rid of that OEM balancer 'while the gettin's good' ... I sleep better now

Makes you wonder if some LS motors had vibration/balance issues that ate HBs.
No they didn't have issues,it's the piece of **** stock balancer's elastomer between the inner and outer hub that delaminates and pinning it won't fix that
I had the first Harmonic Balance for my 2007 fail in 2009 at 28,000 miles. It was under warranty so it was replaced with a GM one. Then at 80,000 in 2017 it was replaced again with a GM one, At the time I didn't know there were other options. For the third one I'm going with the PowerBond PB1117SS which is made in Australia. I almost went with the Summit C-2501 since it was recommended by C&S Corvette Shop on YouTube and it looks nice, but it turns out that it's made in China. I'm at 90,000 miles now so that second one didn't last very long in terms of mileage.

when my HB went after about ten years I had it replaced with a new OE one, that failed within six months. There is a history of poor quality with OE balancers. In a job as expensive as a balancer replacement it’s really not worth the gamble of going OE. IMO

A harmonic balancer is not a consumable, an calling it one to suite your argument is wrong. By your definition almost everything on your car should be a "consumable".
The factory balancers suck, period, and its been well documented. The inner elastomer usually gives way to wobbling. Also they have a tendency to spin on the snout.
Also why replace a failed part.....with the same part that failed in the first place? Sounds like you justifying using a sub par part.
C6 harmonic balancer failed 5 months
