Np203 help

I have a 66 4x4 with 78 running gear. It has a NP203 transfer case that is giving me a hard time. As far as I know you are supposed to have it in HI for daily driving but it wont stay in that gear. I just had it shipped in from CA and the truck driver had it between gears so it was grinding when he started it and I think it screwed up the gear, fork, or both. Who knows how long he let it run like that before he got here.

The way it is now if you run it in 2HI Lock the RPM'S are HIGH (3500) but i'm only going about 40/45 MPH

Are the gear ratios the same for 2HI and 2HI lock??
Can I just pull the front drive shaft and run in 2HI lock until I have time to pull it and rebuild it?

Thanks for the help
