Does this crank pulley look wobbly? So I've been chasing this belt squeal issue on my LSX with a Magnuson TVS2300. Checked all pulleys including water pump, ps, alternator, etc. All seem great. I just noticed the crank pulley seems wobbly! Look at the video I attached and tell me what you guys think? BTW it is squealing really bad, I had just sprayed some WD40 on it and it went away for a few minutes when I made the video.

Oh and Idk if it matters but if I spray some WD40 on the crank pulley the squealing goes away and then comes back a min or two later and comes back almost instantly if I rev it up.

Ok so my plan was to get an Innovators West 8 Rib kit at some point, so why not a better time than now instead of messing around with it again and again. Yep pulled the trigger on it and their crank pinning kit as well 
Hopefully I will not have a hard time finding the right size 8 rib belt now

Hopefully the crank snout is within spec, double pin may hold it more concentric than a single
It took me 4 hours to drill 1 hole in the car and about 20 minutes to drill 1 hole out of the car
Get a good drill bit and good luck

I wouldn't go that far yet - why not mark it to make sure it's moving?
Use a silver marker or paint pen and mark the outer balancer ring, the rubber and the inner hub to make sure the outer ring isn't moving.
Then mark the bolt and balancer to make sure the bolt didn't loosen up?
I installed 3 different LS3 crate motors and every one of them had a fairly bad belt squeak - I changed each one out a Continental belt and the noise went away.
Something worth trying?
