Tap the "acorn" nut covers lightly with a wrench, or such. The two with the solid sound, 180 degrees apart, are the ones that will pull off and expose the nuts that will remove the wheel simulators. You should have a tool in your vehicle that will fit these large nuts. A small 3/8 inch bar, or so, will insert into the hole in the end of this tool-- should give you the leverage to remove the retaining bolts--- Good luck
