Gimbal violently vibrates

[funnyman850]

Recently I crashed my drone. Into a tree and it fell in a pond. I got it back to working condition by replacing the OFDM Module and the Ribbon cable for the gimbal along with re-calibrating the gimbal motors. I noticed a heavy jello effect (https://photos.app.goo.gl/jI6RT8Du6l6WZyzg2) (I took multiple takes to make sure I didn't get the vibrations as they are intermittent). I checked all the arms and it looks like none of them are bent. Here is a video of the vibrating. The AC is not in FPV mode. https://photos.app.goo.gl/1xdLv2KhKjI49Ccq2

Looks like a damaged Yaw motor.

Looks like a damaged Yaw motor.

I was thinking that might be a problem but one thing that I noticed is that the yaw movement worked fine when I tested it.

might be best to strip it down and look for any damage
