Durring practice on saturday, the body of my rear shock came loose from the top. it leaked about 5ml of oil out before i got it apart and tightned it. it SEEMS to be working the same dispite the loss of oil... but i know that can be the case. is it possible to refill the shock myself? or is it gonna have to get sent out? and if it has to be sent out, is it worth it to get it rebuilt with one of the push programs?
