What Doug said. 
Just a WAG on my part but I've always thought: when/if you put a [specific] Load on the suspension, that changes the geometry of the D-shaft.. and spring sets.. to a certain degree.... That.. could cause the "groan" (shudder), when things torque up... when we put things in motion ?
A set of Air Bags is a good way to maybe counter that ?
I've always had "Bags", on all my trucks. Never had this issue ?
