How in god's name do you remove the lower lateral arm?. I've removed the 2 other bolts with ease, but the first one next to where the rotor is just won't come out of its place. I've been at it for hours. Is this thing threaded in? I've removed the nut, but the bolt won't move at all. This is the only bolt holding me from removing it to replace it. This is the drivers side front wheel btw. Anyone can shed some light on how you went about it. Thanks.
