WITH the hoses connected, the next step is to position the jack itself. You’ll want it flattened as much as possible to ensure an even lift. If lifting a rear wheel, you need to position the bag under the chassis or rock slider just in front of the wheel. Front wheels will be the same, but behind the wheel. In either case, ensure it’s in a location that can support the full weight of the vehicle without causing damage to fuel tanks, lines, or the jack itself.
