Question about rotating/indexing driveshaft

I've got a vibration/knock in my shifter that is speed dependent (noticable at low speeds), so one of the things I'm going to check is rotating the driveshaft to see if that helps.

Rotating at the transmission side should be easy as the yoke can only be flipped 180 degrees, but what about at the differential end? Do I need to rotate it by removing the 4 bolts and rotating the driveshaft, or do I just disconnect the u-joints and rotate the flange 180 degrees? Should I also disconnect all 4 u-joints at both ends and just rotate everything by 90 degrees?

I'm an Engineer, so I tend to overthink things. :D

thanks for asking this. I do worry that maybe the person who removed the driveshaft previously didn't put it back the same way it came off, so even though I put it back the same way after putting the tranny back in, maybe it was wrong all along.

I will be looking forward to the responses in this thread.
