2019 Suburban harmonic balancer wobbles
Hi all, new member here. I'm always lurking in the shadows profiting from all the knowledge everybody posts but I finally decided to make a profile because it was about time. So lately I've been noticing on our 2019 Suburban vibrations squeaking noises at startup and then I noticed that the harmonic balancer wobbles. Now I'm a pretty knowledgeable amateur DIY mechanic and I know it's not supposed to do that anybody else having an issue? I have included a video of it. Anyone replaced a harmonic balancer on this model? Thanks for all your input. Here is the YouTube video of the harmonic balancer since it won't let me upload it. https://youtu.be/o0rN-AZDaME

It looks to me like it was not manufactured properly, assuming its not loose. You will need to get the bolts off, then use a puller to get it off. Need to get the serpentine belt off too, as well as the fan and fan-shroud. More Asian junk most likely as the harmonic balancer could not be bent like that..
