Drivetrain noise identification

My 16 4x4 TRD OR makes a clunk noise when going into drive and I can't quite pin down where it's coming from. It's done this periodically since I've owned the truck but it is more frequent now.

Facts:
I recently did the 30K service and can confirm the transmission and t-case are both full or oil.

U-joints are torqued and greased.

I had 4.88 diff gears installed and it has made this noise before and after so ruling out RP noise.

Does not appear to be axle wrap.

Has never made the noise when cold i.e. sitting over night.

Sounds like it's coming from midship.

Here's a vid I took when I was thinking rear brake play or axle wrap.


Right now I'm thinking slip yoke but curious what everybody else thinks?
