Rear axle end play

[1949B-1-C]

Hello! I just replaced my rear inner axle seals and outer bearings. Everything reinstalled and went back together fine however I was just wondering if there is or should be a small amount of end play? After doing a little bit of driving I noticed a small amount of and play developed just wondering if this is normal. It is the same on both sides thank you for any help
