Remove your roof. Ensure your vehicle is fitted with a roll bar or roll cage before attempting the following:
Park under a large tree with a thick, secure branch above the vehicle. Make sure the branch is 1.5 vehicle widths adjacent from the side you are jacking up. If you are jacking the right side, the branch should be 1.5 vehicle widths to the LEFT.
Remove the front and rear under body trays using ramps. Remove all ramps. Next, use the rear rail jack point (the 50-50 balance one) to raise one side of the car with a low profile jack, using a hockey puck to protect the coated metal rail. Then, place a ramp under the raised wheels, lower the low profile jack, and replace it with a full sized hydraulic truck jack or any other jack capable of lifting 2ft+. Remember to use a hockey puck to protect the vehicle from scratches and sliding. Once you reach the limits of the larger jack, place an old twin mattress or two on the ground, with the thin side between the front and back wheels of the non-raised side. Ensure the mattress is centered beneath the tree limb. Secure a chain around the tree limb using a heavy duty screw-locking D ring Carabiner or equivalent.
Tip: ask a friend to help you with the following step.
Gently roll your vehicle off of the jack onto the mattress. Your vehicle should now be gently resting on top of the mattress with most of the weight applied directly to the roll cage or roll bar. Secure several climbing ropes around the far front and far rear jack points, using figure 8 knots and a safety. Connect a second Carabiner to a hand operated winch. Connect the opposing end to the chain, suspended from the tree branch with a third Carabiner.
Lift the upside-down car completely from the mattress by about 3 ft. With the help of your friends, lift the car until there is slack in the chain, winch cable, or rope harness. Count to 3 with your friends and abruptly let go of the car, letting it fall until tension is restored to the chain.
Start with only a slight amount of slack in the lines, repeating this process as necessary until all leaves have been shaken loose from the radiator.
