If it is part-time converted, you can run with the hubs unlocked in HI or LO. You just want to put the transfer case in LOC for a few miles every 100-200 miles though to keep oil pushed up into the tail housing.

Got ya. How do you identify ifyou have a part-time conversion? Thanks for the info by the way.

If you have the same symptoms as the original post in this thread, then your NP203 has not been part-time converted.
