2. Move the seats forward and turn the wing nut on
the cover counterclockwise to remove it. For crew
cab models, reach under the rear seat to access the
jack and wheel blocks. To reinstall the jack and
wheel block assembly in the mounting bracket,
insert the tabs into the jack base by pushing the
blocks up into the assembly. The outer hole in
the jack base aligns with the tab on the bracket.
When reinstalling, make sure the jack is secure,
but do not overtighten the jack in the bracket.
3. The wheel blocks and the wheel block retainer can
be removed by turning the wing nut
counterclockwise.
Put the wheel blocks at the front and rear of the tire
farthest away from the one being changed. That
would be the tire on the other side, at the opposite
end of the vehicle.
4. There is also a wing nut used to retain the storage
bag and tools located under the front passenger's
seat. To remove it, turn the wing nut
counterclockwise.
