Reattach the wheel blocks (E) to the tire retainer plate (C) and tighten the wing nut. 5. Reinstall the tire cover onto the spare or flat tire. Follow these instructions to store the jack and tools: 1. Lower the jack completely. 2. Place the jack in the mounting bracket. 4. Place the tools in the bag. 5. Slide the securing clip over the bag and secure the bag to the floor by tightening the wingnut (B) to the stud coming out of the floor. In order to reduce the potential of the jack squeaking or rattling, you will need to preload the jack so it fits tightly in the mounting bracket. To do this, turn the u-hook/clevis at the top of the jack clockwise until the jack is held tight in the mounting bracket. 5-91
