i have a 99 suburban 2500 and i was driving today and just lost all drive. put it in 4wd and drove home. played around a bit at home and no power is making it to the rear drive shaft. i replaced my transfer case about 3 years ago with a remaned. when in 4wd if i switch to 2 wheel drive it goes and can move as long as there's tension in the drive if i go to neutral and back there's nothing. could their be a problem with the selector pushing it into neutral or something?
