3. Insert the hoist end
(open end) (F) of the
extension through
the hole (G) in the
rear bumper.
Be sure the hoist end of the extension connects to the
hoist shaft (E). The ribbed square end of the extension
is used to lower the spare tire.
4. Turn the wheel wrench (H) counterclockwise to
lower the spare tire to the ground. Continue to
turn the wheel wrench until the spare tire can be
pulled out from under the vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire
not to lower. See Secondary Latch System on
page 5-105.
5. Use the wheel wrench
hook which allows you
to pull the hoist
cable towards you to
assist in reaching
the spare tire.
6. Tilt the retainer (D) at
the end of the cable
when the tire has been
lowered, so it can
be pulled up through
the wheel opening.
7. Put the spare tire near the flat tire.
