I have a 2006 ram 2500 4x4. I was driving down the highway when I suddenly lost all my gears. Thought it was my tranny at first but my driveshaft spins in Neutral, drive 1 & 2 yet doesn't move. ABS light on as well. Is my rear end completely shot? Broken axle? Truck only has 72k miles.

 

What's the fluid look like? Any noises or anything funky before it gave out?

 

haven't had time to check it out but I just changed the fluid last year at 62k miles. But no noises or anything weird whatsoever. Just went out and when my driveshaft is just spinning there is also no noises at all.
