Sorry for not posting in a while.
The NV was totaled back in Aug 2016.
I did not buy another NV. Due to snow and roads here I went back to a full size AWD van and the local dealer service dept is a joke so I'll never buy another Nissan regardless.
The above replacement axle is the correct part # per my invoice.
No long term results on tire wear due to short time with new axle but it looked promising.
I still firmly believe that even the new axle has too much camber for a straight axle.
