2014 Sportsman 570 Front Differential Leak

Hi everyone,

Recently Purchased a 2014 Sportsman 570 used via a private seller. Has about 975 Miles. The only problem I can find is a slight leak from the front differential. I have already purchased two seals online, just waiting for them to be delivered. The differential has a some play, I have attached a video, is this amount of play normal ? I am now wondering if I will also have to replace components inside of the actual differential…
