HI all newly in a c6 from my c5 I currently noticed a harmonic balancer wobble and a chirp and have read it is quite common. Anyone have recommendations where I can get this done and not lose the whole season? I know driving it like that is not a great idea.

If I wasn't so busy I'd give you a hand, I've swapped out my fair share of LS engine balancers.

My recommendation would be to get the Dayco 10% underdrive unit. I've run this on my old C5 and my current LS Swap RX8 and have never had any problems with AC/Alternator performance. It is also a single piece unit so it doesn't have an elastomer to go bad like the stock balancer. Worth it for <$50 difference. You would need a shorter belt, but it's a good maintenance item anyways.

RockAuto is the best place to get parts in my experience. Great prices and the cost they quote you is what you pay, no surprises at the door. (Don't forget to google coupon codes, they ALWAYS have a 5% off code)

Thanks for the reply, and the recommendations seems tuff to find someone to do this everyone says its to long of a job to do in the busy season... gm dealership wouldn't give me a quote unless I booked it in said it's to old for them to quote..... and they also wont add an aftermarket part if I did book it in.
