After the engine comparment is ready for its seperation the chassis is next. In the wheel wells we need to disconnect the brake lines from the body and get any ground straps and the small connectors in the brake system (wear sensors and speed signal sensors) Trans shift cable , fuel filler neck , big chassis to body connector in the left rear. the washer reservoire will stay with the frame so any harness and washer lines need to be disconnected as well. there is also an evaps line in the left rear corner thats easy to forget about. Get all the body bolts out of there and set the vehicle on the ground. Move your lift arms to the body and let the air out of a couple tires so the chassis doesnt move around while your working with that.
