Xreas is a closed system, there is no way to change/add fluid.
My transmission is a closed system as well, and you can flush and replenish fluid as well...there has to be a process for this one would think...but again I might be thinking to much!

He's right!
You're right! You're over thinking.
The fluids in those other systems you mentioned typically break down over time from heat. In the case of the transmission and power steering, the fluid can also be contaminated by particles from moving parts. Flushing those systems at interval is a good PM idea. The xreas system isn't subjected to the same heat issues as the others and contamination is virtually non-existent. Unless they've developed a leak and have lost pressure, there's no maintenance to do on them. The only service you can do on them is to remove and replace. If you do have to replace them, an aftermarket system such as Icon or Overland Warehouse is so much better then the factory xreas. When I replaced my xreas with Icon suspension, the difference was night and day. I kept the removed xreas compontents for a little while then eventually threw them in the dumpster.

your trans also has a drain plug and a fill plug. The Xreas does not, atleast from my memory. Ditch Xreas and go with something else.

The XREAS suspension system is a self contained high pressure hydraulic system, you cannot service the components, if a shock pair fails (even if one is leaking, both shocks and the damper must be replaced) all you can do is replace it. If you replace them yourself, make sure you do research, these are high pressure systems and could cause harm or serious injury if you do not take the proper precautions when replacing.
That said, at 100k the valves inside the system are probably worn or wearing out, a good rule of thumb is around 50k tho start considering replacement on average.

Yes it does. Drain plug on the bottom of the pan and fill plug is on the passenger side of the trans about 2/3 of the way back towards the rear. It should have WS stamped on it.
:iagree:
You cannot disconnect the XREAS hydraulic lines connected to the shocks at all. Once fluid leaks out and air enters in, the system needs to be entirely replaced. There is no way to flush or recharge the system. So this job requires working in the wheel well with handheld spring compressors. Additionally there is the Skid Control Sensor wires right there that cannot be stretched or damaged. Same goes for the brake lines. Various shops I spoke with would have nothing to do with a job like that, with them taking responsibility for potentially runing an expensive XREAS or ABS/Traction/Skid Control system, and not being able to use their wall mounted compressors.
