There's one thing that certain -- it'll be harder to repair if you keep using the tractor!
Block the front wheels up with jackstands and lift the rear-end up with a good floor jack.
Put the transmission in high gear. Range selector in high range. Shift into 4WD. Spin the front wheels by hand. Listen for "bad" noises.
Disengage 4WD. Put the transmission and the range selector in neutral. Spin the front wheels by hand. Listen for "bad" noises.
This can help you to determine if the problem is in one of the front wheel assemblies (planetary gears or bearings) or in the 4WD transmission.

I would do what AKfish recommends right away... replacing a gear, bearing or a shaft is one thing...replacing the whole front end assembly (or something more serious!) is a whole nuther level of $$$$$.
(I didn't see where you said you checked the gear oil in the front differencial?)
