Remove 4X4 option to front wheel two wheel drive only

I think spider gears in rear end are damaged (not certain) from over driving in 4x4. But regardless would like to make this vehicle a front wheel 2 wheel drive only. Can it be done?


The vehicle operates under a torque distribution system with selection knob on dash. In 2 wheel drive selection. The vehicle will go to 4x4 automatically if needed and detected by spinning or lost traction.

A 2 x 4 vehicle will still serve our needs so hoping it can be converted at minimal cost of course.
