Why do you think the front axle fluid should be changed from hydraulic oil to gear oil?
Talk to a drag racer...
There is a lot of stress on the bevel gears when in 4wd and traction is good while turning. IMO a good gear oil, especially a quality synthetic will provide some cushion...much better than a hydraulic oil.
My manual stated the factory fill HYD or a 80/90 gear oil...on the font axle and finals on the front axle
I used 80/90 shaefers synthetic at the 50 hr service.
My qualifications....old guy, broke **** before..... TIFWIW
