Good point.. and I came to this same conclusion on further thinking... 

So.. how about two shackles that pivot in the *same* direction?  Say the 
forward shackle pivots forward, and the rear shackle pivots forward.. the 
4-link would locate the axle, the spring could still elongate and shorten 
based on weight and compession..
