It seems like I don't have all my transfer case positions, right now I have the front driveshaft off but when I go through the gears it seems like Hi-Lock is the only High that works, neutral I can find and the two Low positions I can find also. There seems to be no regular High, just High-Loc (all the way back). It seems if I move it up, it will go into the regular High but when I put it in gear there is just a faint grinding sound. The T-case was rebuild 2 years ago and has rarely been used. Any ideas?
