Very frustrated. Replaced accumulators a few weeks ago. Ride improved for three days and then went back to bumps and thumps. There is no rear suspension. I flushed the oil when I did the accumulators.

Today I cracked the bleeder screw on the level controler. Oil is full of foam.

At my wits end with this thing. I loaded the truck with 150 kg like the manual asks in an attemtp to get the level control lever to the fill position. Only after bouncing on the bumper, I am 255 lbs, did the system respond with a little rise. The right side wheel arch is 25.5 inches from floor, the left side 24.5. Tire pressure the same in both rear tires.

Any help?
