Now I'm assuming That the viscus (which is on mine) will be ok as it will just operate as normal, it only locks up when either one of the front or rear axles is moving at a different speed to the other (slipping on mud) with no rear prop shaft the output shafts to the front and rear will be rotating at the same speed, the only difference will be there is no load on the rear...... does that make sense! or am I going to damage something? 8-[
