I have a slight squeaking noise coming from lower part of my engine. I called up a shop locally here and I was told that it might be a harmonic balancer gone bad.

How can you for sure tell your harmonic balancer has gone bad with out having to remove it from the car? I have a 2006 LS2 :coffeetime: I greatly appreciate the help.

Do you see excess wobble from balancer?
Check for any wear along edge of belt?
Check tension on belt

a wobble with the balancer is common on LS motors. The balancer is not the traditional 350 balancer

Yeah, the balancer is not a solid piece and can get out of balance. On the one we recently had to replace you could see that the rubber piece in between the outer and inner parts of the balancer was out of wack.
Did you guys replace it with stock one or something different?
