Anyways as long as it's left in 2wd it should be fine right? What about the output shafts? Are they held in somehow or can they pop out without the shaft and loose all the diff/tc fluid?
2wd only engages the rear driveshaft leaving the front diff and front driveshaft allowed to freewheel. PT 4wd engages the front axle, and FT 4wd both axles are engaged but the transfercase just changes the gear ratio. there is not "center diff" just front diff, rear diff, and transfercase. and no, the driveshaft doesnt hold the yokes in place, as mentioned earlier removing the front driveshaft just doesnt allow you to have 4wd part or fulltime. hope that answer your question.
