REMOVING AND INSTALLING THE BODY Your Maxx includes an innovative latching system for securing the body to the chassis. To remove the body for chassis access: 1. Turn the handle 90 degrees counterclockwise to unlock the body latch. 2. Open the latch to release the truck body from the rear shock tower. 3. Gently lift the rear of the body. Do not lift too far or the body will become difficult to remove. 4. Slide the body backward away from the front shock tower to release the front body tab. (Installation of the body is the reverse of removal.) 5. Practice this a few times until you become familiar with the latching mechanism. The more you do it, the faster you will be.
