Is there a TSB on the crank pulley for the 2006 corvettes and is it considered to be part of the powertrain? The pulley has a wobble and the belt makes a chirp sound. I have an extended warranty with powertrain coverage but the company I have the warranty with says it's not covered. I'd truely appreciate any info you can offer me as it is an expensive replacement job.

You might just need a belt for the noise. Are you noticing a vibration from the engine? If not the balancer is probably ok. They never look to spin true

Thanks for the reply. No, the engine doesn't vibrate at all but there is a wobble of the pulley. The belt noice is not really bad just a little chirp and thats not always. I had a couple of mechanics look at it and they both said the balancer would need to be replaced, especially since the C6 corvettes have been problematic with the balancer. Something about the gel on the internal shifting. I'd appreciate it if you had anything more to add.
