I'm not a fan of genuine oils but honestly, hydraulic fluid as well as dif oils I think should be original.
When I had a problem with transfer case it was juddering on turns I changed oils twice with "LR spec" but problem was still there. After some articles and other examples on Internet I changed it with original LR and everything gone(coincidence? Maybe). But since I never used alternative for this systems.
