so I was wondering I have a 2004 GMC Yukon with a 5.3 and I always wanted it to be 4x4 instead of AWD. so I figured the easiest way to do that would be to get a transfer case from another 04 gm 4speed that was 4x4 and then get the buttons for the 4x4 witch would fit right where the AWD and traction control buttons are but I have no clue what else would need to be done would the same drive shafts work, would it throw any codes idk if this has been done by anyone before.
