So I went out and looked at it... the bolt is tight, there is no separation between the rubber and the two metal parts. When I crank the car it spins straight, no wobble or anything I can see. Is there anything else to look for?
The tensioner on the passenger side is oscillating quite a bit with the car running, I think that is probably due for replacement.
Check for alignment of the belt. It's possible it could walk forward or back and still be straight.
Look down the belt from the tensioner as it goes to the balancer, you'll be able to see if it's straight or not.
Also, how much effort does it take to move the tensioner? If it's really lose, that might be it. If the belt is original, maybe it's lost some ribs or stretched a bit?
Dodged a major bullet there because it's easy to replace.
I looked at that too, they are dead even. It looks like that is common where the outer metal part of the balancer walks out, it's dead lined up with every other pulley on the belt.
I think I'll replace the tensioner and the belt. They're not terribly expensive and very easy to do. I might wait a while on the balancer, kind of burned out on working on the C5. I'll just keep an eye on it, but by all the visual/feel inspections, it seems fine. I've seen some crazy shit on youtube where it walked forward like 1"+, the bolt is finger loose, bad wobble, etc.
I'm sure eventually something else up there will break and I'll tackle it then rather than paying a shop. When I had all the front suspension off and a bunch of other stuff, I was already part way there, wishing I would've done it then. I had to losen a bunch of those parts to get the PS cooler in.
