dissasemble them, until you just have the strut portion alone. the “arm” (for lack of a better term) should take quite a bit of force to press it into the strut (say your body weight), and it should return to the fully extended position slowly and evenly… The “arm” should not fall right into the strut, it also shouldn’t be jammed in the fully extended position tell tale signs would include covered in grease that has escaped the strut… ----this is how I checked mine, by no means the perfect method, so I will return to this thread to see the suggestions of others. ---

although not having too much technical work with coilovers, i would assume that there is a way to tell. I would do it much like a strut check. Push the coilover down, it will come up because of the spring, but try to listen to make sure there is still oil etc in the coilover its self. If u cant hear any liquid i would then assume its blown. ---

what Darian is talking about is disassembling the coilover down to the damper, the “arm” he is talking about is the piston. compress it and it should rebound… if it doesnt… she blownz i am sure that is not very scientific, but that is how i check when i have like 25 dampers sitting around and need to figure out which ones i want to put back into my car. yay for the wonderful world of D2’s. ---
