Ok if nothing is leaking then your wasting money on the strut.
Your accumulators are a sphere that has a diaphram in it. One side has a gas charge of nitrogen and the other is the hydraulic fluid that is routed from the strut. The nitrogen can leak out over time and that is what provides the shock absorbtion for the system. No liquid, just nitrogen. So it sounds like your accumulator is the problem, NOT the strut.
