How far along are you? are the axles out?
-If not you need to take out the bolt holding the pin in
-Once the pin is out it will allow you to push in on the axles and remove the C-clips from the end of the axles inside the posi
-You then can pull out the axles, take the 4 bolts that hold the posi in and pry it out of there
-btw the wheels and brakes need to be removed
This is very basic and i probably missed something but might get ya going, good luck
