2014 front diff

ok so i have a 2014 rancher 420 and i was riding this weekend and broke a cv axle. weird thing is when the cv axle joint snapped both my front tires stopped spinning. so what I’m asking here is did i mess anything else up like bearing or something in front diff? i was riding later that night and tried 4×4 again just to see if the one good axle would spin but it wouldn’t. when i jack the 4wheeler up off all 4 tires and put it in 4×4 the good axle still spins but when i grab the tire and hit the gas i can hold it then let go and it will start spinning again. thanks in advance
