Clunk that shakes whole vehicle when clutch it let out or at higher speeds with throttle aplication

This is my new to me 2012 Toyota Tacoma. Im pretty decent at driving manual but I can’t seem to figure out the issue this trucks having, at higher speeds when I let off of the throttle or get back onto it I hear a clunk and it shakes the whole vehicle. Should my rear diff have this much play? Motor mounts and tranny mount seemed fine.https://youtube.com/shorts/-oTzniEOVDs?si=k3ER38TG17cRseIq

Set the parking brake and you should not have any play at all. Sounds more like a u-joint issue than diff.

 

Can’t figure out how to add a video to the post, in the air or on the ground I still have play in my diff… any advice on how to add a video
