Removing Ford Mercury hubcaps is a fairly easy task that can be accomplished in a matter of minutes. You can also do the job anywhere, whether in a garage, in front of your house, in a parking lot or in front of the store where you just purchased your new hubcaps. There is a specialized hubcap removal tool. Unless you plan to remove a lot of hubcaps, however, there really is no need for it. A screwdriver should suffice.
Slide the tool or screwdriver between the edge of the hubcap and wheel.
Push upwards to loosen the hubcap from the wheel.
Move the tool or screwdriver along the edge of the hubcap to free other points from the wheel.
Insert a second screwdriver between the hubcap's edge and the wheel, then pry the hubcap.
Move both screwdrivers to different points around the hubcap and keep prying. Eventually it will come off.
