When I turn the steering wheel all the way through, and move, even slowly, it makes this creaking noise... what is that? :)

that would be yo turn stops
they are just bolts on the spindle and bump into the lower control arm to limit how far the wheels can turn
just buy a tube of grease and apply it every so often, it'll take care fo the noise
nothign to worry about
unless you grease them and it continues
now that you know what the noise is do a search, this has been covered with pics before i think

yes i have the same thing with my X once you put the grease it will stop, if not then repost on this thread and let us know.....
