LS4 Performance - Harmonic Balancer............

Mines on its way out , looking into changing it.

Dealer quoted me 360.$ :l

I can change it myself but i need to know if there is any aftermarket one available , i saw some discussion about it from threads past but it doesnt look like anything ever came to fruition.

Anyone?

If I remember right it was tough finding the part.

What are the signs that the harmonic balancer is on its way out ? Are they visual or you start feeling some sort of vibration ? Just curious

Mine started with a noise, caused a bit of belt slip , now i can physically see it wobbling........

Try just replacing the bolt.

Are they known for breaking?
Never heard of that before , wouldnt that cause the whole bit to come off?

I think I remember someone's loosening up and the bolt can only be torqued once. If it wobbles long enough the hole might get bigger.

No aftermarket support for this that I've heard. Order a new bolt and Balancer from WWW.gmpartsdirect.com

the dealer replaced the bushing on mine and its fine now

I've never seen a Balancer have a serviceable "bushing"? The Balancer itself has rubber separating the inner and outer of the pulley itself to dampen vibrations. Usually this is what deteriorates creating problems.

i have a 2006 impala ss and mine is wobbling bad now and the dealer quoted me just over 1k so 360 sounds amazing because i dont have the time to do this and i need my car...

Thats 360 just for the part , i sourced one for under 300 elsewhere and will install myself.

I am not sure who is quoting $360 for a balancer, but I just bought 2 from my local chevy dealer for my LS4 and they only list for $209.00 and with any kind of discount they can be had for around $150.00/$175.00 or so @ the dealer.

Go thru gmpartsgiant.com to get the balancer bolt and balancer. They sell parts at wholesale cost, so you save big bucks!

You will also need to rent a puller and installer.

In order to remove the balancer, you will need to drop the cradle and use a impact gun to remove the bolt. If you do not have access to one, then you will need to use a flex plate holding tool (GM specific) with a large/long breaker bar.

The balancer bolt needs to be torqued and the streched, so you will also need a torque wrench with a 1/2" drive angle gauge.

This might seem like lots of work, but I can do the whole job in about an hr. Do take your time though, and good luck.

On my old GTP, I've used a pair of vice grips on the flywheel to keep the engine from rotating. There's a small black plastic cover on the bottom where the engine/trans connect. Take out the one or two 10mm bolts and remove the cover to expose a small portion of your flywheel. You won't ruin it with a set of grips. Its hardened steel, and I doubt you can squeeze hard enough to damage it.
As far as the pulley puller, you should be able to rent one from Advance Auto or Auto Zone.

I live in Canada , our pricing is alot different , especially on specialty stuff like this..
And i get 10% above their cost...

I used a prybar on the teeth to hold it in place.
And the bolt is called Torque to yield...

They are supposed to be single use , but a lil bit of lock tite and its good to go...

Dropped the cradle , replaced the HB , and bolted it back up , ill finish the rest off after work tommorow night.

My car was built in Canada.

Just checked mine so was mine.

Shes all back together and running strong.

I wonder if all gxp's were built in Canada?

If your vin starts with a 2 it was built in Canada , a 1 or a 3 and it was built in the USA.

Add my 2006 Impala SS to the list.

Engine was screeching when started during very cold (<10 degrees in AZ) - so opened the hood to see what was up - and although not the cause - saw that the balancer was wobbling.

Replaced today by local Chevy dealer - $186 for balancer, $28 for seal and $616 for labor. Took a day to get the balancer from CA.

Did you pay out of pocket? 616 for labor seems very high

All balancers wobble. I would have had them replace then tensoner too.
