trying to change out break pads..wheel is stuck..will not come off. i see nothing about this wheel having a lock. i removed the wheel nut that is hiding behind the centercap...nothing. all other wheels have a silver 'dome' under center cap this wheel does not...need help 2002 9-3

 

i have had the same problem, i ended up putting in the lugs and then backing them out about 1/8th of an inch, lowered the car slowly and that loosened up the wheel. the left wheel was more stubborn and i ended up just turning the wheels to break it free.
