My E320 with 90k miles has major bouncing in the rear. I did some research and it might not be the air struts but the accumulators. Can someone please point me in the right direction on how to test them. I don't want to purchase new ones if they are working and it ends up being a different problem.

Also has anyone replaced them with a conventional setup? Is it worth it?

Sag I think would be a symptom of bad accumulator/air strut (the spring portion) bounce is a loss of dampening. Needs struts/shocks
