Did you upload the video from the fender as well?
OP, I'm NOT trying to highjack your thread so I hope you don't mind the discussion?


I just uploaded the video from outside of the car, didn't think about that earlier.



The reason I think the RSF is moving is in this video I'm focusing on the shiny part of the cross-member by the muffler in relationship to the black plastic "box" that appears above the muffler in the video. I did put a bunch of post-it notes on my display lined up with the diff, RSF and the chassis to watch parts move, lol. Since I'm working from home I'm using a 42" TV as my computer display and the details look pretty good.
