It was ralativly easy. One of the easier things I have done. Took me just under two hours, would have been finished sooner but I had one stuborn stud.. (took a torx socket and a extension. Hammered on, turned off). I would have had enough thread to use the original studs, except I didn't have enough clearance to use a socket driver on the nuts. Yes.. I probably could have just used a wrench, but I felt better by using the new hex bolts. I actually did the right side without removing the wheel. It was a little snug trying to get the studs out though. By the time I got to the second side, I didn't feel like fighting with clearance anymore... took the tire off. Either way, not that bad.
Kind of assuming its working, it feels like it. Feels a little lighter in the front end driving with them unlocked. But I don't know enough about how Pathfinders are with and without, it would be easier to decipher if it was about 4 months from now when there is ice and snow everywhere. I haven't even owned the Pathfinder for a week and I have done one mod already. I think the CB radio install is coming very soon.
