8.75 clicking

Upon exiting the interstate this morning I noticed a whine coming from the rear. As I slowed down it turned into a buzz, and while turning by hand, it clicks once every 180 degrees.

The sound is definitely coming from the differential and sounds more like it's coming from towards the front of the third member. I've removed a third member before, but my question is, how easy would it be to remove the yoke without removing the third member to look inside?
