“Under no circumstances should an accumulator be pre-charged with oxygen or air. If compressed oxygen or air encounters even a small amount of any hydrocarbon, it can react violently, resulting in an explosion, fire, injury to personnel and property damage. An accumulator should bear a safety sticker that warns against pre-charging with any gas but nitrogen. New accumulators come with such stickers, but they often are scratched off or painted over.”

Nope, not on the LX. Have had to put new boots on a couple times from cracking/slices etc. I've done steering rack twice on my non-AHC 100 with 35's though.

As mentioned, it is not a good idea to attempt to charge 'globes' with anything other than an inert gas such as nitrogen. AHC Fluid basically is a combustible light mineral oil with additives (but not glycol compounds, unlike brake fluid).
Even in ordinary use, some air may enter the fluid in the AHC system. Air under pressure in the AHC Fluid will result in some oxidation -- which is one of the reasons why old AHC Fluid can look very dark as it ages.
There are very high gas pressures behind the membrane when 'globes' are in the vehicle -- 5.3 Mpa to 5.7 Mpa (or 769 psi to 827 psi) -- matching AHC Fluid pressure at FSM specification measured with pressure gauges not Techstream. Nitrogen pressures are lower as delivered from the factory -- but there is no valve or other provision to allow direct measurement of nitrogen pressure behind the membrane.
