no, they aren't going to cover it.

Good news is, a new CV can be bought at Autozone, Advance, etc., for only around $90. And it'll come w/ a lifetime warranty (though I haven't heard of anybody getting them to honor that, for an offroad break...)

CVs on Nissans break by just looking at 'em cross-eyed. I've broken 2 in the past month. They're easy to replace, though, and are a "wearable" part for the IFS...
