Basically, the alignment of these vechicles can be dumbed-down to this:
Do we love lifting our pathfinders- Absolutley
Does lifting your pathfinder cause alignment issues- Yes
Is the alignment system poorly designed on the pathfinders- yes
Do alignment bolts seize up on vehicles- Yes, especially if you live in a region where road salt is common.
Can you bring your pathfinder back to stock alignment after lift- yes but be prepared to spend money. The front is easier than the rear to bring back to stock. The front is simply camber bolts and after market upper control arms (if applicable). The rear requires the bushings and new camber bolts as well.
Can new alignment parts still cause alignment issues- Not usually but it can happen from time to time.
To sum it up: the alignment problems suck after you lift your pathfinder but can be fixed if you spend the money.
