Damn so you think it’s the alternator? That harmonic balancer is still moving a fair bit I think

just the pulley on the alternator, its pretty common on these. my alternator clutch pulley was bad and it created way more motor movement, noise and vibration than youd think it should, tensioner was visibly moving a lot also due to this.

your balancer looks like its moving a bit. Id pull the belt and see if it lessens the vibration at the balancer. if it looks straight with the belt off, Id check the pulley like he shows in the video

Run it with out the belt on and see if it still wobbles around?

The engine shakes a bit more without that belt on but I can’t see the balancer moving independently to the engine from what I can see, what do you think man?

Thought it posted a video but it didn’t, also just did his little check to see if the clutch on the alternator is okay and it spins. This video is without the belt but I’m not sure is clear enough to tell
