Default Do I need to replace my harmonic balancer?
Hello! I’m new to the forums and this is my first corvette. Today I noticed a little wobble in the crank pulley. It doesn’t make the belt squeak or make any noise, I just wasn’t sure if this needed replaced asap or not. Thank you!

Paint a white line on your harmonic balancer. If it starts to separate, you should think about replacing the HB.
