they are usually on there pretty tight. try jacking up the car really high and going at it from the bottom.
so I got the tools the fluid and started, got the drain plug free but did not drain, went to the fill plug, the thing will not even budge, so now I m stuck, can't get the fill plug off so I can't drain the thing, can anyone recommend something here, even tried removing the battery to get some more room to us a longer bar, but there is'nt enough room under there to move the bar, I do not want to have to take this thing to the stealership!!
