I don’t if this will work but would love you all to give an opinion on the suspension video so here is my wife’s Facebook link it’s the only way we can show it https://www.facebook.com/groups/electricvanmpv/permalink/575757316946879/
Windy the road springs (or in some case torsion bars) absorb the road shocks and the vehicle weight distribution, (the dampers often referred to as shock absorbers control the oscillation of the road springs otherwise you would be bouncing around), the majority of modern vehicles are fitted with rollbars to the front and occasionally to the rear suspension.
Like Wigwam has highlighted you may have one or several defective dampers, there is a simple test to check the dampers
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
