Okay, Ill try jacking it up when I get home. Sounds like it might make sense, since I had to compress it to get it to bolt in. Compression felt good, not too easy to squish it flat. The O ring on the post where the silinoid slides on looked good, no obvious cracks. I put some grease on it to help with the seal. The o ring on the little black hose looked okay too, still soft and flexible. Do you think the inside of the strut could have corroded at all with out that silinoid on it? I've got the fsm, so I'll look through the trouble shooting part, though the basic install/removal section didn't help me find the problem. I'm not hearing the silinoid click on or off at all, opening the strut to air, so that's why I think it's the silinoid. funny thing though, cuz before I pulled the strut off, I turned the car around and the strut aired up fine. Now that's its on the new strut, it doesn't seem to work....Hopefully it just needs a jack!
