When chocking the wheel, place a wheel block in front of one of the front wheels or behind one of the rear wheels. 3. Loosen all the wheel nuts. Always loosen the wheel nuts before raising the vehicle. Turn the wheel nuts counterclockwise to loosen them. To get maximum leverage, fit the wrench to the nut so that the handle is on the right side, as shown above. Grab the wrench near the end of the handle and pull up on the handle. Be careful that the wrench does not slip off the nut. Do not remove the nuts yet-just unscrew them about one−half turn. 247
