Well, I just finnished doing one of them and it seems to be pretty good. All I did is fill it up just alittle above where the threads on the INSIDE are. (dont need oil where the shock seal holder is going to thread into) Then slowly threaded the seal into place, this forced out any extra oil, and Air as well. Seems to be working pretty good..So, Fill er up seems to be the answer.
There you go!
