I'm a newbie when it comes to mechanics. I noticed yesterday that only my front wheels are spinning and I have no traction coming from rear wheels. I have a 2002 cadillac escalde with 160,000 AWD 6.0L Vortec. Not sure if its the rear diff or maybe transfer case or if 4x4 went out.

The only reason I noticed is because we had about 10" of snow yesterday and I got stuck. My wife was driving truck so I jumped out and saw that only the front tires where actually moving no traction coming from back tires. We eventually got pulled out by a neighbor. The truck seems to be driving fine, but its strange that the back tires dont seem to be engaging. Any help would be greatly appreciated.

If there is any Cadillac technicians that can help guide me in the right direction on repairing this issue? I think maybe the 4x4 is out or rear diff, but once again I'm no expert mechanic.
