Rear end carrier help needed

I'm thinking bearings from the looks of it when I got it I dont think it had ever been appart but who knows the shims appear to there.

"Some"shims are there, but obviously not enough and in the right places.
If the bearings look good the only thing you can do is to shim it where it needs to be.
The bearings would have to be pretty bad to let it move that much.
