jack the tire off the ground

remove the air valve insert at the top of strut

remove (one at a time) hex bolts and blue locktight 

  (don't let locktight drip inside strut)

push the tire up to collapse the strut.

attach a hose from the valve and dip into your oil

drop the tire sucking oil into the strut

run the strut up and down to remove all air.

push the tire to the top, and remove oil hose

drop wheel, re-insert valve

put 100psi of dry air from local compressor

lower plane from jacks

fly to a friend with N

full both tanks of gas from friends FBO and have two large guys sit on  wing

add N such that you have ~2 inches of strut showing (add an inch)

take friend flying and show how you can "grease" landings with new struts.

yea, I've done this a few times.
