Harmonic Blancer
How many of you have looked to see if your harmonic balancer is wobbling and if it is how much did you pay to get it fixed
|
I replaced mine before it started wobbling. The new ATI damper was about 350 bucks. I did the labor myself as part of a cam swap.

Another very good HB ...
Dayco 'PowerBond' Harmonic Balancer P/N: PB1117SS $ 222.97 Shipped https://www.summitracing.com/parts/p...model/corvette 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 |

I'm looking at a C6 to purchase. How do you know if the HB is wobbling? And to add to my stupidity...where is it??

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? |

Flashlight under the hood looking down from drivers side. If looking straight on from the front end the HB is located about 8 o'clock (for reference).

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 :( |

Some engines will go forever without a problem, while some balancers will fail early in life (it's a crap shoot). 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 NSF |

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

when you bent over for that, I hope they at least used a little lube.

Yep....unfortunate, but that seems to be about the going rate for the R&R at a the stealer ship.

( 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? |
