Another very good HB ...
Dayco 'PowerBond' Harmonic Balancer

Personally, I wouldn't go through all the trouble replacing it until it actually starts to wobble ... Some engines will go forever without a problem, while some balancers will fail early in life (it's a crap shoot).

And by the way .... If you ever do replace the harmonic balancer, DON'T replace it with another OEM balancer.
Unless GM is replaceing it for free

That would be a good time to replace the HB with a quality aftermarket HB.
The HB has to be removed anyway in order to replace the camshaft.

Mine is wobbling a little. (Relative term). I'm under warranty but don't know if they will replace it simply because it's wobbling. However if I wait for it to cause major damage (assuming it will someday) then they will have to replace much more than the HB.
Not to hijack the OP's thread but has anybody had it replaced under warranty simply because it wobbles a bit? I'm sure many techs would simply say "yeah, they all do that!"
Also if they do replace it can I upgrade to a better aftermarket unit and pay the difference?

If it's wobbling, you'll see it.
I paid $250 for the TrickFlow balancer with Continental belts and a $10 GM crank bolt.
I paid ~$800 for installation

So I bought mine from Rock Auto, little more pricey but it was perfect, FYI I'm sure it has been corrected by now as this was about 4 months ago

Chevy replaced mine under warranty. The invoice states it was ~ $1200.00. It probably cost them < $200 in parts/labor.

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?
