After you get the wheel off take a flat screwdriver and light hammer and GENTLY pop the buld on the edges and it should come off quite easy. under that bulb (wich is actually just a sort of cap) you will see another bigger screwnut that actually holds the hub into place. BEWARE: before taking this down carefully check it to see it it's not made of pieces. Ford uses a special tipe of nut that brakes in case you are not carefull (my 2003 Ka has it, not really sure if the 1999 model had it or not). be sure to have a spare one of the same tipe before starting to undo it. after that, just pull the hub off. hint: i take pictures at every stage of the work just in case i can't get it right when putting them back on.
