I need help as far as what the problem could be. The video shows the details of the problem. The issue began today so Im trying to attack the problem as soon as i can. Also there are no leaks from the axle or hub. It seem like there just too much play. Is this an major issue or does something just need to be adjusted. I really appreciate all your help.

In most GM rear ends movement like that means the rear axel bearing needs replacement.
