The first time I looked at the trapezoidal leaf springs setup I thought, cool, less axle wrap, more side/side stability. Then, after a few rides down the 880 here in the SF bay with my fillings falling out, as they say, I gots ta thinkin'
Trapezoidal leaf springs will flex in two planes (i.e. they wont try to just push the axle up/down but side/side too, towards/away from itself?) just think about it, that's how the things work. Problem: shocks in the conifiguration installed on our trucks damp up/down, not side /side. As I said before I'm not much of an expert but i had enough vibrations in my dynamics class to know that any undamped system has the possiblility to reach resonance (freeway bounce in our case).
My opinion only. But interesting thought maybe? Lets hear some thoughts.

Umm, I'm not sure about all the tech stuff, but one thing I can agree with is the fact that I almost lost my teeth during a ride on one of those uneven freeways. I mean my glasses kept vibrating loose off my nose. What the hell were Toyota engineers thinking?
