I would first check for any dilution of the oil by fuel. Does it have a misfire? If so I'd likely perform a cylinder contribution test and locate the misfire, and follow up with a compression test then a leak down most will likely find the culprit if it's blow by related.

Probably have a cracked timing case as well. Another oil leak hot spot is vacuum pump. Probably take a look at those after getting a compression test. If you need to pull it for a overhaul you could do it all at once out of the truck and complete the work much faster.

The disconnect is often called a cad (central axle disconnect) or axle disconnect motor.
