Front Diff Question

Hi, recently bought a used 2009 Grizzly 350. During oil change, I had up on a jack to check over it all. The front right tire was harder to turn than the left, which was easy. So I took wheel hub off and checked the wheel bearing, not those, axle still harder to turn. Very good shape. Removed the axle, and that bearing right behind seal is impossible to turn by hand. Should be it like this or what? I’ve never owned a Yamaha so not sure if just a design .
Any advise or input would be great.
Thanks
