Not So Fast

As some of you know I just had my harmonic balancer replaced with a PowerBond PB1117SS, I was shown the old one and I'm glad I had it done. One edge where the bonding takes place was approx. 1/8th" higher than the other opposite side, hence the wobble. Whether it was about to fail I have no idea but it had become worse in just over the last 6 months. Since they are pretty well hidden from view I think the once overall check would miss them unless you take a flashlite and look for a wobble.
Anyways the new one runs straight and true so just an FYI to maybe save you a little grief

Did you collect the old one?

Should have kept it for posterity's sake.

Glad you got it done NSF

Would this be called being proactive instead of waiting, and being reactive ? I think so.
Good advice, thanks.

Thanks for the heads up. You scared me! I just checked mine. It has 45,900 miles on it and looks straight with no worn belt. Guess I'm lucky.

I checked mine last week. Has 32k miles, and the outside edges wobble a bit but no worse than the last time I checked it -- two (three?) years ago. The belt grooves actually run truer than the outside of the balancer.

So far, I will assume that it was like this when new.

The belt edges are fine, no chirps when cold.

Well the old saying if aint broke don't screw with it holds true My point was CHECK IT to see, if that helps one member from having his grenade then this post was worth it

I know what you watched on TV as a kid. Or maybe you were too old for this . . . ?

I remember them!

You can't miss the chirp. It was so loud other drivers could hear it.

Yep, But i hope we ain't just in denial Bruzey...LOL ....I check mine regularly also. Now has 26-K. It wobbles more than i'd like to see, but still the same as when I bought it and doesn't seem to be getting worse. Like i've said many times here.....I'll wind up procrastinating till it comes through the hood then i'll bitch about it.....

What happens when the HB fails? Is it catastrophic?

I'm surprised that NSF's failed since his car is fairly new and he never drives it.

So am I but that good ole GM quality knows no boundaries. My car has 30k on it but it had the infamous slight "wobble' when I got it over 3 years ago but in the last 6 months it got worse so I wasn't taking a chance, maybe wouldn't have happened but if it did then the cost and damage would be a lot worse
Pay me now or pay me later I guess, not trying to scare anyone but check it regularly

PS catastrophic, if it comes apart at say 3000 RPms, well you guess

Usually the outer hub will move forward enough to destroy the belts and grind against the steering rack. By then you'll know it's pretty bad

It seems fairly accurate to assume that many of these balancers were bad when the cars rolled out of Bowling Green.

O.P. Thanks for the heads up. I am new to C6 ownership as of this June and Today I checked the HB along with other stuff and found for 52k miles and 12 years the balancer and belt looked new with no wobble. Fair to say they are new along with a new Duralast Gold I spotted. I am great full I got a well maintained used Vette so now all I have rattling around in my head is the A4 No shift shifter syndrome to check into soon.. thanks again

My sons HB failed, and the outer ring crashed into the timing cover and put a deep gouge into it. Some members have commented that it can spin the other way and hit the steering rack.

simplegto

I started my car one day and it sounded like angry birds under the hood. No damage other than replacing the balancer.

Just rolled over 50,000 miles and my HB still wobbles a bit just like it did at 3 miles! I'm lucky I guess.

Well this is definitely encouraging to us that keep living with a wobbler <<< is this a word ??......
