I have a 2019 Sportsman 850 with about 35 hours on it . The front diff pinion bearing failed last weekend . It was not the pinion cover but the bearing just Disintegrated . Is this something that just happens? My son has a 2019 HL with the same diff he is running 32 inch mud tires and he has had no problems with the diff . Is there any kind of Upgrade ?

I took it apart the ring gear and the case are ok but the pinion and bearing is gone . I can get the ring and pinion kit for $670 . I can’t buy the pinion and bearing by itself . $1399 for a hole new diff . But how do I keep this from happening again .
