Once youve loosened the lug nuts about a turn each, you can jack up the car. Loosening the lug nuts is much simpler while the tires are making firm contact with the ground. Lifting the Corvette is easier if you have access to a hoist, but can be done with a jack at home. Notice that the hoist has a rubber block so as not to harm the body panels under the vehicle. If nothing else is available, hockey pucks do a fine job of protecting the panels from the metal jack pad. Once again, we emphasize that you should never work on a car supported only by a jack. Put the car on jackstands for your own safety.
