Wheel bearing noise, 91 cherokee?

I've got a 91 jeep Cherokee sport 4x4 5speed. And just recently it developed a noise that sounds just like a wheel bearing going out. Happens at speed 30mph+.

I narrowed it down to the front right. So I replaced everything at once, (both wheel bearing/hubs, both axle u-joints, both axle seals, both upper and lower ball joints, the tier rod end at the pitman arm-adjusting sleeve-drag link, and bot tie rod ends of the tie rod, and the track bar lower bushings.)
Got an alignment, and the noise is still there.

I remembered my transfer case leaks so I drained it (very little and black gear oil.) And then topped it off with fresh oil and took it for a drive. Noise seemed to be gone. But now this morning on my way to work the noise was back and just as loud.

I doubt it's the front axle bearings by the diff. I also doubt it's my rear axle, because the whole axle was rebuilt completely with an Eaton Detroit locker. (Ford 8.8 axle)

It could be my front driveshaft (it's the 4 driveshaft I've swapped in one year) or the rear driveshaft. But I don't believe u-joints would imitate a wheel bearing howl.

Just a month ago I changed engine oil, transmission oil, and front and rear diff oil. (Obviously forgot the t-case) so I don't see how an internal bearing could be going.

And like I said it's dependent on speed only, not engine rpm.

Any brainstorming is greatly appreciated.

(I do know that I need new heim joints on both of my long arms at the chassis end.)

You should've bought a Japanese car

Likely your Tcase. You said black gear oil. What tcase do you have and what fluid did you put back into it? The NP231 and NP242 Jeep transfer cases call for ATF.
