I have some question about the symptoms and diagnoses.

- if the nitrogen spheres go bad, the suspension gets stiff, but there's no effect on height, right?

- if the struts go bad, the car rides low, but there's no effect on stiffness, right?

- I see wagons with the rear level and low, but always even left to right. Is it not common or possible for only one strut to fail causing listing?

And a general question:

- what is the function of the nitrogen spheres?

MB purists should skip this question:

- is it possible to retrofit old fashioned air shocks with an air compressor and adjust the ride height manually? Maybe Gabriel should reconsider their product naming strategy these days.

Thanks,
Sixto
