Okay, so heres the science! Dogbones and universal joint axels spine the wheel at a varying rate if the axles aren't parallel to the ground because the pivot point and engagement point( where the dogbones touch the diff. i.e. the little nubs that stick out.) This makes it so that the rotational force is now trying to make the axles parallel to the ground instead of spinning the wheels. CVD's, or constant velocity drives have the pivot point in the center of rotation. This means that as long as the axle doesn't make a 90 degree bend, it will still spin at the same rate. This causes the suspension to move freely without the axle trying to hold it still. Somebody just needs to come out with cvd's that are easily removed from the diff side so you can have a true cvd.(have two joints on one axle, not one and a dogbone.) JIMMY you should understand this. it's like a four bar link or horst link on a bike. When you pedal the susp. is still free to move. (and braking too)
