Yeah usually they have a circlip that locks them in... can be a turd sometimes. Get a prybar in there and repeatedly tap the cup of the CV joint with a hammer.
I've honestly never seen a Fusion with appearance mods. Or really mods of any type. They're such a popular car that theres a million stock ones out there keeping any modified ones hidden.
Off to google now...and i can't recall who had that Cougar either....was it blackNredCougar, or someone like that? Seems his name was Rick?
I dont remember, but he was from Ada, OH. Down near Lima. Im not even sure if he did the work on it. But I'm guessing whoever clamped the vac line going to the wastegate to 'remedy' a boost leak (thus overspinning the turbo to death) probably also did the brake lines.
