The tools you will be using include
the jack (A), the wheel blocks (B),
the jack handle (C), the jack handle
extensions (D), and the wheel
wrench (E).
1. Do a safety check before
proceeding. See If a Tire Goes
Flat on page 10 78 for more
information.
2. If the 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.
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.
