Well, they are calling it a torque sensitive limited slip differential but i dont see any reason why it wouldn't be a pretty loose open diff in its current configuration. Me thinks that changing the the angle of the peaks and valleys on the face cams would affect the "limited slip" function you might feel from the differential. If I'm thinking correctly, with a steeper angle you would be able to transmit more force to the stuck wheel... but I'm guessing Honda has found what they think to be the optimal angle. I think this type of diff would really work well with the whole i4wd electronic braking system.It is in the front and rear for the pioneer 1000 with out i4wd. We didn’t know that we had limited slip differentials in the front and rear because it still seems to spin one wheel very easily.
I don't really like those pics that Joey posted above though. Obviously this diff is relying on friction between the face cams and followers, and it shows in the pics. Seems like a high wear item, vs a regular gear diff, but with clean thick oil it is probably fine.
Having said that though, if I broke a front axle and had the i4wd system then I wouldn't count on being able to get any power out of that remaining wheel up front.
