If it drives in diff lock but not with diff unlocked your problem is between tcase and hubs
If still no drive with diff locked the problem is somewhere between tcase output and engine.
Could go either way. Others have had similar loss of drive and noises and its been gearbox/clutch. Ive had same symptoms and its been axle once and diff another time.
Just another diagnostic that takes very little time and narrows the possibilities quite a bit.
