Hi everybody, i am from estonia and im going to apologize in front if my english is bad. I have a problem with my s124, the rear end makes a real loud banging noise when i drive through potholes or rough ground, i was thinking about changing all the bushings in the rear subframe but noticed the other day that my sls isn't lifting when loaded, could it be that the noise and this sls problem is all coming from the accumulators, the oil resorvoir of the sls is full and there doesn't seem to be any leaking marks on the struts.
