Rear end blown??? Need help!

[Kashmoney05]

So I think the rear end is blown. It makes a loud popping noise like it’s skipping a tooth. When it is on jackstands and you accelerate it doesn’t make the sound. When one on the ground and you accelerate it makes a loud popping noise. Any kind of advice or suggestions would greatly be appreciated. Thank you

Attached is the YouTube video clip I made for it

check the running gear attachments to the frame, I had similar symptoms, but in front, when I was in 4wd backing up. My frame was broken and running gear was pulling away and skipping.

I had frame welded and gusseted,  I've beat the crap out of mine, logging, but I think what did the damage, was snow plowing, hitting frozen rock solid snowbanks in frigid temps
