A few tests to work out what is wrong.
First look at your front diff. Does it have a seconds smaller housing on the left side of the main diff. If so you have Tod or Sof and that is most likely the problem. If you have this still do the following even though some tests will fail the following and let us know for a new set of tests. For starters TOD and SOTF should not have free wheel hubs although some people fit them for a small ecconomy advantage. Also if a locker has been fitted you need to fit free wheel hubs
1 Car in neutral and 2wd Free wheel hubs unlocked
Get under car and turn one cv joint by hand Watch the other cv. It should turn probably in the oposite direction. If it doesnt see if the drive shaft is turning. If it is put the car in 4wd and in gear and repeat.
Repeat from other side
This test is for the spider gears and as long as you can make each cv turn from the other side it is a pass.
2 out of gear and 2wd
Lock one free wheel and turn the oposite cv. Driveshaft should turn. Repeat for the other side The oposite cv should not turn
3 Put car in gear and 4wd one hub locked
You should not be able to turn the oposite cv. Repeat on other side
If all these pass you are probably looking at a gearbox problem
Sanding your knuckles before starting work can help. That way you cant skin them
