The upper and lower arms are not just coming back to the diff housing in a straight manner from the body. The lower arms are at an angle going towards the outside of the car and the upper arms are on an angle going towards the centre of the diff. Thus you get a triangulted (spelling) set of traling arms if you looked down on the setup from above. This of course helps for torsional loads. The upper arms being shorter than the lower arms will rotate through their travel on a shorter radius that the longer lower arms. Thus when the diff moves up and down in the suspension travel it is moving through an elliptical arc. A better option is for the diff to move up and down on a fixed radius, to do this you would have to have upper and lower arms of the same length (in track cars they cut two slots into the floor pan and box them up, thus creating enough room for the upper arms to be the same length as the lower ones). The panhard rod is there to keep the diff centred as it moves through the travel. Hope this helps a little [Report message to a moderator]
