Torque Boxes vs. Frame Connectors

So what do you think was the root cause of the tire shake? Were the leaf spring bushings worn out? Was there an excessive amount of frame flex? I've never had trouble with a Mopar having a wheel shake (or hopping) problem. I'd always heard that the design of a shorter leaf section in front of the axle prevents it.

worn out leafs
body twist
not enough tire for power output

yes, the short spring hits the tire harder

I was trying to find the pics I took
the sheet metal was moving/ separated where the inner fender panel meets the fire wall

after the 3rd pass/window fell
and was hard to open drivers door
then had to lift up to get door closed

circled area
I didn't notice it until the car was on the rotisserie

its warped/ pulling apart on both sides
car has never been wrecked that I know of

So this winter, we took the car ALL apart to fix those issues
I hope
