I was also getting a loud noise under acceleration. Hopefully after all the work i did the noise and wobble are gone.

As noted, most of them wobble a little. When it gets worse, that can cause other problems and may be a sign it's about to separate.
Ours has had a slight wobble for 89k miles but no changes, so still good.
There is a GM bulletin about how to measure wobble, it's a PITA because you have to remove the belt and use a dial indicator in the groove. The other surfaces are not precisely machined and are not reliable for either a visual or dial indicator check.
Good luck, be careful but don't panic.

That didn't look too bad to me and I didn't hear any chirping, but I'm on mobile so take that with a grain of salt since I can't really hear anything on it.

word ty guys for your input. whew well i just found out my friends 06 has the same problem. however his was wibbling like crazy and he has 140k on it hahaha. his mechanic which is the corvette mechanic at our chevy dealer said it was probably doing this for 100k so in truth i am not worried about plus read that on 05s its much more of a thing to worry about. whew and my *** is saved once again

There were a small number of early 05's that had a problem with the crank bolt getting loose. Totally different problem. The balancer used on the 05 is the same one used on every other year and it's junk.

Yours is not wobbling....it looks like mine if not better...forget about it and drive it like hell.
Here is mine... I did a ton of research on it and I am simply keeping an eye on it but from what I found out this is normal and can last essentially forever like this. I will not fix it until the belts start chirping etc and the wobble increase.
