For Yukon, the equipment is located behind the left trim panel in the rear of the vehicle. Unlatch the release lever to open the trim panel door. Skip the first step and follow the last three.

For Yukon XL, the equipment you will need is under the storage tray in the driver's side panel.

1. Remove the tray to access the tools.
2. Remove the wing nut used to retain the tool kit by turning it counterclockwise.
3. Release the jack from its holder by turning the knob on the jack counterclockwise to lower the jack head.
4. Remove the wheel blocks and the wheel block wing nut by turning it counterclockwise.

You will use the jack handle extensions and the wheel wrench to remove the underbody-mounted spare tire.

10. Spare Tire Lock (If Equipped)

1. Open the spare tire lock cover on the bumper and use the ignition key to remove the lock, if your vehicle is equipped with a spare tire lock (J).



2. Assemble the wheel wrench (H) and the two jack handle extensions (I) as shown.




Insert the hoist end (open end) (F) of the extension through the hole (G) in the rear bumper.

3. 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 .





Use the wheel wrench which has a hook that allows you to pull the hoist cable towards you to assist in reaching the spare tire.





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.

5. Put the spare tire near the flat tire.
