Question "slipping" on acceleration

For a little while now, my X is experiencing what I can only describe as a "slipping" vibration - stutter in acceleration, variable in internal. It does not happen at idle, only acceleration. My thoughts:

1. Clutch
2. Rear diff
3. CV

Clutch seems most obvious, but not sure how to confirm other than to replace and hope for the best.

I say rear diff since I also get a slow speed thunk from what appears to the rear/driveshaft, like it is unloading pressure, when coming to a stop or in a slow speed parking lot scenario.

I say CV because I know I have a front right boot tear, but other than that, I do not get any noticeable noise from it. Just letting it run its course until I have no choice but to replace.

Thoughts?

i believe this is called 'clutch chatter' and happens just about on engagement.

rear diff would howl/hum or start to heat up more than usual, and eventually just internally let go and you don't move

cv would click click when loading in a corner
