Any vehicle can dislocate it's springs if you try hard enough.
If you're going to go to that sort of axle-movement, you need to also think about extended brake-lines; long-travel shockers; castor-corrected radius arms; and wide-yoke propshafts.
Personally, I've clamped my springs in place, so they don't drop..... and don't re-seat "off-center"
