Well, I bought a front axle from the salvage yard and did the swap. Unfortunately after my daughter had been driving it around for a while the ZJ broke down on the side of the highway. I went to retrieve it and the front pinion gear is shot again. I'm guessing the VC is bad and caused the pinion gear damage.
After I brought it home I pulled the drive shaft, ring, pinion and axle shafts out. I had two old axle shafts that I cut down so the bearings didn't separate. I'll be doing a NP242 swap within a month or two.
We have a slanted driveway and about 30 minutes after parking the ZJ I found it had rolled into the street. I noticed that the Jeep very slowly rolls back; you have to really watch it close to notice it. I've never seen this before, would having a bad VC cause this? Or is it because I have no front driveshaft?
