You would be running two different sets of wheels and lug nuts due to different bolt and thread patterns.
No locking hubs.
steering may be an issue if depending on how you lift your truck do to steering linkage configuration.
Also the Pathfinder is a hefty pig compared to the jeeps I would think so durability may be an issue.
I also do not know what the gear ratios in the D30s that you would have to find to match your pathfinder.
Also, you can find d30s for next to nothing so if they break you could just replace the whole axle and scrap the old.
Again, I'm not all too familiar with the dana30s so take my advice with caution and do your research.
