Put the spare tire near the flat tire. 1. Insert the socket end of the extension on a 45 degree angle downward into the hoist drive shaft hole.

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 5-75 for more information. 5. Position the chisel end of your wheel wrench in the notch of the center cap and pry off the center cap. 5-69
