So I've heard but I've tried from that side and can't see it. Mine is only visible from the drivers side. And clearly so. 2010 GS. I dunno'.
Maybe what I'm thinking is the HB is clearly some other pulley and my HB is completely wobble free, as anything I see from the passenger side is running true. It is only the lower left pulley only visible from my drivers side that wobbles. If it isn't the HB then what is it?

Next time you are out my way, stop over and I'll show you what to look for.
I can also show you my ATI balancer.

Did it myself for ~ $308 with very high quality parts.
Harmonic Damper PBB-PB1117SS $215
ARP Balancer Bolt Kit 234-2503 $34
Crankshaft seal ACDELCO 29602 $15
Belts CONTINENTAL 4040410 CONTINENTAL 4060798 $29
Power steering fluid $14.5
Borrowed some tools - torque wrench, puller - from local autoparts "loan-a-tool" program. Was a pain in the A, but doable. Took about 10hrs (probably longer than most) and needed a second pair of hands to take the rack in and out. Make sure you seal the keyway and bolt to prevent oil leak. Plenty of videos on youtube to walk you through it.

I had mine replaced by a local, trusted, mechanic with corvette experience. Went with the ATI in std size. It came to $900 for all.
If you're wondering what a wobbly HB on a LS2 looks like, here's a video of mine...

Dan, you may be looking at something else. You saying it is at 8:00 o'clock also makes me think you are not seeing the balancer. It is attached to your crankshaft right in the middle of the engine.
Next time you are out my way, stop over and I'll show you what to look for.
I can also show you my ATI balancer.

I should come by and get your eyes on it. Also you can probably tell me from your experience, assuming it is the HB, whether or not it needs to be done soon. I'll give you a shout out, maybe after the holidays and scoot on over.
And Merry Christmas to you and Dee.

I want to hear from somebody, anybody, who has personally had an HB actually fail on a stock LS2/LS3. We are all out there replacing our HB's like *****'s, and more than half the people who own C6's don't even know what it is, where it is, or what it does. They just drive on, miles upon miles, and we never here of a single incident from anyone it personally happened to.
I'm not being contrary, but I have yet to read of one, single, failure on a stock LS2/3. Have we unnecessarily created a cottage industry of HB replacement???

I have read about 3, maybe 4 failures on here in the last year or so. I go between C6 General and C6 Tech and don't recall exactly where I read the posts, but there are a few on this forum. If I recall, the balancer jams into the steering rack and shreds the belt. A lot of noise but surprisingly not any major damage on the posts I saw.
I don't necessarily doubt that a failure could happen, but would like to know if there is much evidence that it does.

For me it was like this, I looked and saw a wobble, it had gotten worse over a short course of time, then I thought about my car when it was on the dyno with that pulley spinnin at around 6000 RPM's, that was enough for me 
Maybe it would have never failed, maybe, but I didn't want to take the chance so it was replaced and now running straight and true
Take it for what its worth, its your car

I have heard that, too, but did not read it. I have tried everything I can think of to find those posts, and have not been able to. the only I actually found concerned a failure on a supercharged motor HB, which does not impact most of us. I realize what the likely outcome of the failure is, but I am looking for proof that a significant threat exists on base, non-modified LS2/3 engines.
I don't necessarily doubt that a failure could happen, but would like to know if there is much evidence that it does.

Also. If the balancer is wobbling and the belts are chirping then the part has FAILED. Just because the pullies aren't flying out of the hoods doesn't mean they haven't failed. If the part is no longer working to spec it has failed. Wobbling too much is failing.
Catastrophic failures are very rare. Probably because then the belts start chirping the part is getting replaced before it does fail catastrophically.

My Vette is '05 and I see from the VIS report that the HB was replaced at 37,000 miles under an extended warranty purchased by the original owner. The car only has about 45,000 on it now and all is well.
