ATI Harmonic Balancer Wobble
Has anyone heard of an ATI balancer going bad? It wobbles enough to concern me, but nothing looks loose or sounds off.
A friend of mine is suggesting the apr bolt is loose. I’d hate to take everything apart just to check that bolt.

did not have a single failure with the development of the LS1 engine in the 200,000 mile certification.

Spoke with the last two owners and it was on there when they bought it so it’s been at least 30k miles since install.
Video barely shows wobble but trust me, it’s very noticeable in person.
Sorry for the short clip. Any larger of a file and it won’t attach. You get the idea.

It's hard to tell by the vid, and I am sure you are concerned. I see at least a 1/2 inch space between the balancer & the rack and the belt seems to be lined up with the wear mark in the tensioner.
If you are saying and seeing a bad wobble, the only thing you can do is replace it. You will be removing the rack and you want to get it right. You have to remove the rack just to check the torgue on this @ 245 ft lbs

Maybe I’ll hold off messing with this anymore for now as it doesn’t seem to be causing any issues.

My factory balancer was wobbling, so I'm replacing my harmonic balancer today. I choose a Fluidampr.
Not a fan of old school rubber bond between two chunks of metal.
I like that Fluidampr provides a different way to solve the problem and that the outer case is all one piece.
I have a 2006, Z51, with 6 speed automatic.
