Trans Output Seal Leak

[94GrandPrixSE]

Replaced the half shaft a few months back and didn't replace the seal. Its dripping trans fluid from the output seal Is there any tips on replacing the seal (Passenger side) I couldn't find any write ups. It seems pretty straight forward but I thought Id ask first.

Remove axle...remove old seal...clean area....install new seal using old seal as a driver...lube axle...install axle. Done.

Thanks it was pretty simple. I used a 2" pipe fitting to punch it in evenly. I noticed my newish half shaft that goes into the differential has a small amount of play horizontally and vertically is this normal?
