So today I notice under my car I have a balancer wobble. I have the bbk under drive pully that'sthe piggy back ddesign, looks like its just the pullys wobbling not the hub itself, but I'm thinking about replacing the hub and trying to just run the bbk under drive only,
Is that safe to do since thestocker is neutrally balanced?

Wait...you are saying you want to run without the harmonic balancer?
I'm no expert, but if that is your plan, I wouldn't recommend it. It's there to absorb crank vibrations. Without it, harmonic vibration can damage the crank.
My pullys are wobbling that's my main concern, I haven't thrown or damaged a belt yet. But its starting to worry me.

You mentioned BBK pulleys....so obviously this has been apart at some point since it left the factory.
Have you inspected it far enough to see if the pulley bolts are just coming loose, or if the pulley is actually worn at its attachment point? If it's just the fasteners, perhaps a good cleaning and some blue Loctite?
I've checked now and it looks like one of the bolts is stripped. I have a new hub laying around, anyone know the correct bolt thread numbers on these?

I have a stock balancer .BBK under drive pulley and crank hub with the under drive pulley already installed. .. if your interested 35 bucks and I can get it out tomorrow or Friday if that ends up being your problem. ..
I might be interested in that, I'm going to try new bolts and see if that helps. If not I'll be getting ahold of you

I bought some new grade 8 bolts, have yet to install anything (been lazy) but the bolt thread type is 7/16 14 I'll post up my results when I get everything in. Looks like the tq specs Re 60ft lbs on these right?

[MENTION=3929]dawdaw[/MENTION] any pics of your hub and damper? Seems like I'm going to need another. Tried new bolts, no dice.

So both those pullys and the hub correct? I have the same smaller pully. It honeslt looks like my bbk pully isnt on the crank hub evenly

Ok so found out there was some dry RTV in the hub where it mounts to the crank snout. I'm still going to replace it, so now I need a crank hub and damper,
