hey i just replaced my shafts in my shocks how and or wat do i do wen i replace the oil????

just fill it get all the air bubbles out, put the cap on and bleed the excess out so the shock rebounds about half way out.

Probrably wouldn't hurt to change your seals and o-rings as well. Normally its just a couple of bucks so why not.

Get your owners manual. If you don't have your owners manual, search for an online version. Depending on which company, it should tell you how to re-oil your shocks step by step.
