Kickr v3 Freehub Bearing

I have the 2017 v3 Kickr with Shimano freehub, and the freehub bearings are cooked. Does anybody know what size they are? The trainer still works, with unhappy noises, and I would like to get the bearings first before taking it apart to replace them. I would really hate to have to scrap it over a $10 dollar bearing. I’ve tried Wahoo support, with no luck.
