2014 Grizzly 700 Outlaw Axle HELP!

hey guys, new to the forum.
i am helping a friend with his grizzly as we are trying to go ride this Saturday!
we have ran into a problem last week.
he has a 2 inch high lifter lift, and 28 inch ITP mega mayhems.
he right side factory axle broke so he ordered an upgraded outlaw axle from high lifter.
the only torque spec we could find was 190lbs
seems way to high to me, but that’s what we tried and the new axle snapped in less than 50 feet!!
the torque spec on the axle nut is the only thing that we can think of that we might have done wrong.
we now have another axle (another outlaw dht) and are in a time crunch for ride time so any help would be awesome!
we don’t want to repeat the same results! lol

so basically, what could we have done wrong? and is 190lbs seem right to you guys??
we used a nice snap-on torque wrench that we know is accurate.

BTW, this is the right side rear axle. the new outlaw axle just snapped at the outer joint closer to the hub. ripped the boot apart and everything.
