Styled Steel Wheel Shown
If you have a standard steel wheel, carefully pry along
the edge
of the hub cap until it comes off. Be careful, the
rim edges may be sharp. Don't try to remove the hub
cap with your bare hands.
If you have the styled steel wheel or aluminum wheel
with plastic nut caps, loosen the plastic nut caps with the
ratchet and socket. Make sure the
DOWN side faces you.
To remove the hub cap from the aluminum wheel
without plastic
nut caps, fit the flat end of the extension
into the notch. Then, remove the center cap.
