Rear end carrier help needed

I just got done putting my 8.8 back together after shortening it and when I put the axels and the clips back. I noticed that when I push on the axle there was a noticeable clunk so I pulled the cover back off and I can see the carrier is sliding back and forth it looks to me like the movement is in the bearing I'm thinking bad bearings but I'm not 100 percent sure. I have not disassembled or removed the carrier from the housing until yesterday when I found the problem I hadnt even broke the caps loose. But I did pull them to try and get a better idea of what going on. I have three videos I uploaded to YouTube I will share the link to help you help me lol.
