12 xp noticed when going slow there will be an intermittent grind/vibration witch will make rzr not wanna move like the brakes are on slightly but if I stop and back up a couple feet then drive forward it’ll be fine for 1/4-1 mile then it will come back and I can repeat process. Does it in high and low 2 or 4 WD it also. I’ve checked clutches and belt. I pulled tires and inspected brake calipers. I pulled prop shaft cover and inspected carrier bearing and it seems fine it will pry change it anyway
