Axle Play at the Diffs

I nearly crapped my pants when I checked my 2008 Big Bears axles at the diffs, all 4 had up and down play when a pulled on the green spindle part. 3 had about 1/8" of play and the front left had about 1/4" of play. I quickly check my 97 Kodiak – it had no play on either of the front axles at the diff.

I only have 700km on this ATV and I’ve changed the diff gear oil at each 100km interval. It always clean, no water or metallic shavings and the seals don’t leak. I’ve never had a problem with this ATV, no grinding or anything.

I quickly did a search on this forum but nothing came up. I can’t see all four bearing being bad this soon, is it possible that this play is normal?
