hey mike tangas

as I said before, getting the cellsis kind of hard but if it is necesary I will.
Supposing there are bubles trapped in the back of the system, if I take them out and leave fluid only, will the bouncing get worse or better?

Even if you bleed all of the nitrogen out of the system the ride will still be hard. The continued hard ride will eventually ruin the rear struts. The accumulators are what provide the shock dampening.

If the spheres cost $500 each where you live, struts will probably be $1,000 each.

Someone mentioned a filter. Where is it? I see the strainer thing (like the one in the master cylinfer) but nothing else.

The fluid recycles to the levelling valve, only. After the levelling valve there is only a "goes into" line to the accumulators and then from there to the struts. The struts are no more than a hydraulic ram, that sets the ride height. All the damping effects come from the accumulators. When they fail the entrained Nitrogen goes into solution with the oil, and stays dissolved in the oil, in the accumulator area. When you crack the bleeder valve the oil from the strut goes out the supply line and you get this foaming action as the oil comes to atmospheric pressure, and the Nitrogen comes out of solution.

Allowing the car to operate with the fluid in the system "solid" which means without a compliant cushion of pressurized gas will fatigue the Aluminum mounting threads in the strut mount to the suspension (bottom of the strut as it is mounted in the car). The strut is a steel extrusion and has a male thread at the bottom that engages female threads in the Aluminum mount. When the fluid system is solid the response to road irregularities you feel as "bouncy" begins to overstress these Aluminum female threads and they eventually rip out. The fix is a new strut. They are about 4 times the cost of a Nitrogen sphere.

If having items like this shipped from Germany is feasible, get in touch with Andreas at www.dbdepot.de since I have recently purchased a strut and a set of spheres I can report the cost was about $95 or so for each sphere and about $300 for the strut. Shipping brought the total bill to about $550. Make sure you get a proper wrench for taking the lines off the spheres, as rounding those little guys is a major problem. My son got impatient and ruined one, and had to use a Dremel tool to cut the sphere off the line. Then he had to restore flats so he could wrench the thing again. He spent at least 4 hours under the car on one side, and then with the flare nut wrench of the right size and a few applications of a pentrant, the other side came off in a few minutes.

Good luck and I hope this helped. Jim
