Differential Seals?

This doesn’t seem right.

2015 700 Grizzly.

Bought brand new last May. Already went through 2 seals coming front the front drive shaft to the front differential. The seal itself is on the differential end. What could be the problem. :/

If it’s the vent hose for it where is it located? I wouldn’t think it’s clogged up. Never suck it that deep in mud. But then again who knows.
