is the tranny in gear whne you try this? i have found my tcase doesnt want to shift for beans if the transmission is in gear
sounds like your clutch isnt releasing completely
It's called driveline bind, easy to get from 4Low to 4High and a pain to go from 4High to 2High.
Try rolling/rocking back in reverse then shift.
Mine does the same thing.
absomalutley back up till it pops out, i try to never have mine in 4 hi when on a hard surface
