I have the same issues on my '99 500 Sportsman........I looked at the "wires" going to the struts........appear to be no more than sensors on the disc backing plate
The shaft turns free and so do the half shafts...... the front tires spin freely...no drag whatsoever.
Mine has the slide switch that shows "AWD" when moved to the left.
I did pull the hub and all I swa was a alloy 2 piece disc with rollers held in place with a large "O" ring that rotated in a smooth race......how in the

does that take the torque
Apologys for asking before offering but I have reached a wall.........
This looks like a fun place!
