This video is with the car in drive and the e-brake on with slight gas
Hi everyone! I just want to say thanks for all the help in the past…. Here’s something new

I notice this only when the car is in drive
It used to be only with the AC is ON…. But now i’m starting to hear a rattle/grind when the car is initially accelerating. Keep in mind when i’m in park it does not do this (even after revving!) and only the AC makes the occasional noise (still an annoying rattle coming from that)

I know it's hard considering it’s a video. But any suggestions related to this would help.
I think it could be due to the rear motor mount in the video(i have a part coming)
But i’m not sure

Something loose in the muffler? The catalytic convertor inside stuff loosened?🧐
