    in the middle of a DHX air rebuild, need some assistance please

    Hey all, I'm wanting to rebuild my dhx air 4.0. It's from a 2006 specialized enduro. So there is no boost valve on the back of the piggy back. I know I can't recharge the bottom out like all the other dhx air's. I have the main body off and apart. But the real problem is the shock needs new oil and a bleed! (squishy) Pretty sure that the boost valve and the main shock are all inline. So by trying to bleed this, will I depressurize and loose the bottom out. Possibly blow this thing up in my face?

    Yes, do not open the shock without depressurizing IFP chamber.

    If I depressurize the ifp, how do I recharge it? there is no valve to fill it?

    You can't do a rebuild without depressurizing that shock. I'm not sure what kind of a valve your shock has but usually if there isn't a "traditional" schrader valve sticking out of piggyback that shock might have either recessed schrader valve (needs adapter to pressurize) or rubber plug (needs a needle adapter to pressurize).

    You need a nitrogen needle and a new nitrile plug.
