Thats a different story. The accumulators still work the same way. The struts now are taking all the load. There are 5 accumulators on that system.
You mention replacing a lot of parts but you don't mention adjusting the height valve, which would be the first thing to do. The front struts are supplied by separate valves and are adjusted separately. The rear has only one valve like the load leveling suspension. The adjustments are turn buckle links that attach the valves to the suspension.
Tell me if I misunderstood the question.
