New guy with some questions.

The NP203 is fine.

One note: The oil for the rear output shaft bearing is provided by the chain spinning and throwing oil up into the ways to keep the reservoir filled, and the chain does not turn if the front driveshaft is not turning. So when driving around with the hubs unlocked, put the transfer case in HI LOC the first time you drive every day, for the first couple miles, then you can switch from HI LOC to HI while on the roll. When driving long distances, put it in HI LOC every time you stop, for the first couple miles, and again switch from HI LOC to HI on the roll. This will keep you from eating up output shaft bearings.

Not running around in HI LOC or LO LOC on clean dry pavement with the hubs locked will keep you from eating up chains and tires.
