Would you just add air or nitrogen and assume fluid is there inside?
    Thanks for the advice!
    If it is not wet I would just service with nitrogen.

    I believe if you try to measure the pressure with the load of the airframe/engine resting on the strut, you will lose a lot of air and be sad.
    As I mentioned above, after pulling the lower cowl, it's easy to pull the tail down either with weight on the tail hook (or a couple friends on the inboard-most part of the stab) to fully extend the strut, then pump it to 130~135 psi. While you have it extended you can wipe some hydraulic juice on the exposed chrome to remove any dirt - I just squirt it up into the seal/wiper to flush out the crud, and wipe up with paper towel.
    After a couple tries you will get the feel for it. I usually adjust it during annual when I have everything apart and the nose wheel off for bearing service.

    Cheers,

    Does anyone have a complete written procedure for replacing the seals in the front strut? Thanks.

    I looked by keyword and did not find a complete "procedure" here.
    There are a lot of helpful tips, search "nose strut", "strut wiper" etc.
    I think an enterprising fellow could cut & paste the various suggestions into a cogent procedure from start (Remove engine cowling) to finish (Reinstall engine cowling).

    It looks like the answer to your question is “NO”.
