Been researching and trying numerous solutions to solve a vibration I have in the rear end of the jeep, it can be felt in my seat from 50-63 or so mph, after that it either fades out or isn't as noticeable. I have played with pinion angle in the rear anywhere from -2 to +1 and no change, I have gotten the tires balanced twice in the past week and hasn't changed the vibration. Rear driveshaft is an Adams that is less than a week old, front is stock. There is no change if I remove the front driveshaft. Motor mounts and trans mounts are new. There's no play at the pinion in the rear, the SYE output may have the slightest movement that can be seen when really pushing down and up at the edge of the seal (If I had to guess 0.2mm). The vibration is pretty aggressive and nothing is jumping out as being super loose or very wrong . Im stumped at where else to look.
Edit : Forgot to add, vibration still happens in neutral coasting at that speed
