Alright, so I'm driving a 92 v6 4x4 truck, i drive to work and at the end of the day, pulling out onto the road i hear a pop and the truck stops moving. I thought it popped out of 1st, so i jam it out and back into 1st real fast to avoid getting t-boned. Nothing. I pushed the truck back into the parking lot and peek under it. The driveshaft is spinning, I'm assuming either the pinion gear sheared off, or an axle broke (open diff?) I limped it home front wheel drive. If anyone has had this happen, share please! I plan on fixing it this weekend, but my time is very short, if i can pull an axle and pop a new one in that's the best- case. There was zero grinding, or any new noise on the way home. Any insight is greatly appreciated.
edit: the pop wasn't very loud, i really thought it just popped out of 1st.

 

No way to tell what's what without raising both sides of the rear end and doing some twisting and shaking.

Does sound like a broken axle though.

 

left axle...

 

This happened just out of the blue like that?

 

You running stock size tires? Put a blower onto that V6 engine? Any guesses what might have induced this failure? I don't believe it's common on a stock truck.
