If the wheel has a smooth center cap, place the
chisel end of the wheel wrench in the slot on
the wheel and gently pry it out.
1. If your vehicle has
wheel nut caps, loosen
them by turning the
wheel wrench
counterclockwise. If the
vehicle has a center
cap with wheel
nut caps, the wheel nut
caps are designed to
stay with the center cap
after they are
loosened. Remove the
entire center cap.
2. Use the wheel wrench
to loosen all the
wheel nuts. Turn the
wheel wrench
counterclockwise to
loosen the wheel nuts.
Do not remove the
wheel nuts yet.
