Rear suspension height not level

[Davezj]

have you checked the tops and bottoms of the springs as it has been known in the passed that a spring can snap but only at the end top or bottom and effectively lower the car, but still work as a spring.
you would only have to loose one turn to make a large difference. I have seen/heard more and more reports of suspension spring snapping lately and most people are putting it down to speed bumps, continuously hitting these with a large force is going to put a massive strain on the spring and shock. So having a major impact on the rear end as in you case could very well snap coil off.
