Check first to be certain the 2 spd. shifter on the diff. is all the way one way or the other. If it's electric, you might even have to pull the motor off & turn the shifter drive by hand. If it's an old vacuum shifter, disconnect the diaphragm & move the shifter rod in & out. If the shift collar in the diff. somehow gets stopped between ranges-- just like neutral.
