Sloppy Front Axles

2013 850HO XP, Put Rhino axles in when new, 2k miles on machine and I noticed where the axles go into the splines ( front Diff) there is a lot of play almost like something is worn. The bearing is tight and doesn’t move around, I put the stock axle (which is still new) in and that has the same movement (a lot) anyone got any thoughts on this??
