Front wheel nut that secures wheel hub to cv-joint came loose in my 2002 Maxima. Nut was backed up to the cotter pin. Also, this happened last year on my wife's 2000 Maxima. I think Nissan made a bad design decision when they chose not to use a locking washer/nut for this design. I have a jpeg picture of resultant wheel wobble.
