Strange Noise from Drivetrain

[clean2g]

I checked them when I replaced my clutch in August when trying to diagnose another problem, and I rarely drive the car. They all seemed fine. The only one I couldn't confirm 100% if it was ok was the shitty designed rear motor mount that you can barely reach. I felt it with my hands and everything seemed intact, but that was just from feeling it and visually seeing as much as I could, I hope that's not it because I have no idea how to replace that without removing the motor.
