It sounds like the gears are not meshing up properly, is the shifter cable activated or electronic.

Does it drive in any gears in 2WD ? Rev, low or high ?

If it drives in only some gears when in rear wheel/2wd drive then it looks like it will be in the gearbox. Drain the engine oil and check it for metal dust.flakes or lumps.

If it doesn't drive in any rear wheel drive gears, then you should check the rear driveshaft is turning, and not making the noise, and if it is turning, then drain the rear diff and check it's oil for metal dust, flakes or lumps.

If the rear drive shaft isn't  turning then it's lost it's drive between the shaft inside the engine that takes the power to the front and rear driveshafts. There's a long shaft inside the engine that rotates and both the front and rear driveshafts slide onto it with a spline. The long shaft must be turning because you have drive to the front, so the rear driveshaft may have stripped it's splines where it slides on at the back of the engine.
