My solution as the parts were too expensive to replace is to use it for only short distances and on smooth roads. I also keep tylenol for the headaches the bouncing can cause.
Very rough ride, bouncing and semi-erratic sways from rear end of wagon. Tried adding self-leveling fluid from dealer, no improvement. Mechanic recommended new accumulators which are specific to the car, very hard to replace when it came to tightening lines so as to not strip the threads. Turned in to a four hour repair but so worth it. As soon as car was started the new suspension was charged and it rides like a dream.
