Front hub excessive play

I'm in the process of changing my front diff as it ate a bearing!
I seperated the hubs from the swivel/axle (seven bolt) flange and have them stood up in the wheels.
I was checking them over and noticed the that when you hold of the N/S (long haftshaft) halfshaft it has quite a bit of play (when turning it) compared to the O/S (short halfshaft).
Is this wear in the CV?

Thanks

Matt
