Bmx freecoaster side to side play

Hello, my freecoaster seems to have a bit of side to side play (not very noticable in the vid but you can kinda see theain hub body separate from the little sprocket as it wiggles from side to side). I have tried some things to fix it (take the whole thing apart twice and rebuild and tightening the cones as tight as possible. Are there any other solutions to fix this? Or will I just have to deal with it? Thanks
