Your vocabulary is fine --- describing some of this stuff is difficult when trying to do discussions like this via "the web".

Thank you all for the help. I have the problem solved.

Both bolts that go through the springs were broken. This allowed the leafs to shift fore and aft; affecting suspension movement in unpredictable ways.

Bolts replaces, axles centered, all good!

You might consider stouter leafs in the car. The Global West L2's are dimensionally larger, enough that you can use the isolator pads in the perches.
They aren't exactly plush riding though.
