I found what was causing the rattle, next step is seeing what to do to fix it. I tightened the bolt but it still rattles. Only stops when I put my finger against the bolt and hold. I'm thinking of using a foam washer or similar, and I'll see if the dealer has any ideas, have the oil change coming up.
I realize now that the previous video and probably this video you can't hear the ticking off normal speakers. I'm able to hear it with volume up and with headphones on or right up against my phone speaker.
