Not really sure on this one.

I think either one of my U-joints is shot or i accidentally smashed my driveshaft into something while offroad.

At about 35 seconds you can hear the noise i normally hear when i'm driving. It almost looks like the driveshaft is waving at me and isn't spinning true. (like it's out of balance or roundness or something.)

On Friday i replaced the centering pins on the leaf springs and i added another shim to the leaf pack. Old shims broke so i replaced the old shim with a new shim (same degree shim) and then installed a new centering pin. I think it's unrelated but i don't know.
