I needed to replace my rear wheel bearing in my X this week and I was having trouble finding one that fit. I had several places order them in for my exact vehicle, yet all of them were too small. After measuring the bearing I removed from my Xterra, I searched NAPA's website and found my bearing to be the same size as an '02 Pathfinder wheel bearing. I thought this was strange. Anyone want to chime in on this?

Anyway I can tell if I have a different rear end thean most X's or anything else?
