Crank hub?
 

Hey guys. I had a pretty bad wobble on my harmonic balancer. I replaced it, and there's still a small wobble. I think I have to replace the hub. My question is.. where the heck do I find it?

I've checked ebay and my local part stores. I found two online. One is keyed, and my balancer is not. The other one looks kind of odd and is also keyed..

Any ideas?

Before wasting any more money, pull your hub off, run the engine, and look to see if the crank snout itself is wobbling.
Some nit-wits have been known to jack up the front of the engine by the lower pulley, and then bending the crank.

wow 76 bucks,,, #10128273 GM Parts Direct: Your direct source for Genuine GM Parts i dont think the keyway makes a difference., at least the one i bought said it worked with either.

Oh wow. No part of this motor has seen a jack. I'm not that dumb. lol

This is a new problem. I've had the car for over a year now. Still think it's a possibility?

And thanks Craby. I might buy the one they have on Jegs.

Wasn't referring to you...but a previous idiot! ;)
"This is a new problem"...what does this mean, what was the tip off? Did you just start to experience a vibration, or do you not have a vibration at all? Is it possible you always had a wobble, but just now noticed? Crank hubs don't just "bend" on their own. Seriously, save your money for now till you remove the hub and inspect the crank.

Still haven't messed with the crank hub, been pretty busy lately.

I have an odd question though. My car has the newer version of the optispark with the piece that has two o-rings that go into the cam. When I was replacing it the oring on the top got messed up. I peeled it off and stuck it in. I'm wondering if this could cause the vibration that I'm getting. From what I read it stabilizes that shaft. Interested in what you guys think.
