AWD engages when front tires are in the air

OK guys, when I was in the RZR community, I swore I read that lifts somehow caused the 4wd to engage sometimes with stock axles. Not sure how or why, and can’t find that information anymore.

My problem; when ‘water-wheeling’ the bike, the AWD will activate sometimes. It has never happened with all 4 tires on the ground. I had the front diff apart during the build to install the aluminum sprague and it’s in great shape. Is it somehow caused by the lift creating too great of an angle when at full droop? Is this a problem that can be solved by axles? Not sure how to proceed.

So far, it really hasn’t been a ‘problem’ as I am running slow and easy on the throttle when the front end is up, but of course I would like to remedy it if possible. Thanks!
