I am ready to declare this a pattern myself, and that stinks. Nothing should break with stock tires, that is really short sighted and pathetic. Montero guys run 35-37" tires on stock drivetrain with very little breakage, and only on the most extreme trails, and NEVER A FREAKIN DIFF EXPLODING!
So you throw 35s on and a stock CV cannot handle it...dissapointing but not the end of the world, and Nissan cannot engineer for everybody. Pull out a universal CV from the trunk, change it on the trail and be on your merry way. But explode a diff, and you are totally screwed, not to mention $$$$$$.
All I have to say is thank goodness for Xterra Racer, and hopefully the warranty period lasts until the new front parts come out.
