Allright, I pulled the driveshaft. Nothing wrong with the yoke.. It's only a metal edge which looked like a crack in the video I made. I made another video of the output shaft play and rear end / R&P play. I think the noise I'm hearing when shifting is coming from the rear-end.. You can see how much noise this makes when turned. Normal or excessive?
