That's pretty much it. I suspect that if I mounted a gopro, I would see the same kind of stuff. I can tell you I don't have the balls to keep driving it knowing that problem will happen again though. It violently shakes the truck, and actually causes my throttle linkage to smack the master cylinder. I may or may not have a motor mount issue as well. Need to verify that when I pull the thing apart. I keep looking for a frame crack at the springs mounts, especially because I have that strange popping noise when my front springs articulate. I should have time to pull the springs this weekend so I can get a good look for worn bushings or broken leaves/hangers.
