GMC Chevrolet Silverado 2500HD 2021 Owner's Manual page 360

The tools you will be using include the
jack (1), the wheel blocks (2), the jack
handle (3), the jack handle extensions (4),
and the wheel wrench (5).
1. Do a safety check before proceeding. See
If a Tire Goes Flat 0 355.
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,
concealing access to the wheel nuts,
place the chisel end of the wheel wrench
in the slot on the wheel, and gently pry
it out.
If the wheel s center cap does not
conceal the wheel nuts, the center cap
may remain during wheel removal. If the
removed wheel is to be stowed in the
hoist, the cap needs to be detached from
the wheel. Access the wheel from the
back side, and use a jack handle
extension to push out the center cap.
