5. Turn the lug wrench clockwise
to raise the jack until it lifts the
secondary latch spring.
6. Keep raising the jack until the
spare tire stops moving upward
and is held firmly in place. This
lets you know that the secondary
latch has released and the spare
tire is balancing on the jack.
7. Lower the jack by turning the lug
wrench counterclockwise. Keep
lowering the jack until the spare
tire slides off the jack.
8. Disconnect the lug wrench
from the jack and carefully
remove the jack. Use one hand
to push against the spare tire
while firmly pulling the jack out
from under the spare tire with
the other hand.
9. Tilt the retainer and slip it
through the wheel opening
when the spare tire has been
completely lowered.
10. Turn the lug wrench clockwise
to raise the cable back up if the
cable is hanging.
Have the hoist shaft assembly
inspected as soon as you can.
You will not be able to store a spare
tire using the hoist assembly until it
has been repaired or replaced.
