The tools you'll be using include the wheel wrench (A), wheel blocks (B), extension(s) (socket end) (C), handle (jack end) (D), and jack (E). The following instructions explain how to remove the underbody-mounted spare underneath your vehicle. Notice: If you remove or restow a tire from/to the storage position under the vehicle when it is supported by a jack, you could damage the tire and/or your vehicle. Always remove or restow a tire when the vehicle is on the ground. 1. Insert the socket end of the extension on a 45 degree angle downward into the hoist drive shaft hole. It will be exposed when the rear gate is open and is just above the rear bumper. Be sure the socket end of the extension connects to the hoist shaft. 2. Turn the wheel wrench counterclockwise to lower the spare tire. Keep turning 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 5-77 for more information. 5-71
