The sagging isnt the shocks though, thats all in the leaf springs and torsion bars.
This is it, the shocks will not effect the ride height at all, you could remove them with no change.
The torsion bars and rear springs will sag over time but I cant see it causing an all of a sudden lean. I would be looking for broken leaf springs, possible bent hanger.
