Mike hit it right on the head. Anytime you strengthen one component, that weakness moves up the line. So if you strengthen the hubs, the next weak point is the CV. Beef up the hub and the CV, next stop is the front-diff and so on and so on. Hub is WAY easier to replace on the trail and much easier on the wallet.
BUT, there is really nothing wrong with the OEM hubs compared to going with Mile Marker (which is junk) and Warn manual hubs. There is a youtube video somewhere of an xterra blowing two Mile Marker manual hubs on the same obstacle. Blew one, replaced it with a spare, then very next attempt, blew the other.
Also, unlike the pathfinder and most other IFS 4WD vehicles, when the auto-hubs are disengaged, the CV axle is disengaged as well. So you do not have that rotational resistance that affects your mpg's and wear on the axle. Pathfinders and 2nd gen xterras only disengage at the wheel in 2WD so the CV axle is always turning.
