JACKING

Print

The standard jack uses slots in the frame, or bumper to raise and lower the vehicle. Do not attempt to use the jack on any portion of the vehicle other than specified by the vehicle manufacturer. The jack supplied with the car should never be used for any service operation other than tire changing. Never go under a car that is supported by a jack only. Always block the wheels when changing tires.

The service operations in this guide often require that one end or the other, or both, of the car be raised and safely supported. The ideal method, of course, would be a hydraulic hoist. Since this is beyond the resource and requirement of the do-it-yourselfer, a garage or floor jack will suffice for the procedures in this guide.

Two sturdy jackstands should be acquired if you intend to work under the car at any time. An alternate method of raising the car would be drive-on ramps. These are available commercially or can be fabricated from heavy boards or steel. Be sure to block the wheels when using ramps. Never use concrete blocks to support the car. They may break if the load is not evenly distributed.

Regardless of the method of jacking or hoisting the car, there are only certain areas of the undercarriage and suspension you can safely use to support it. See the illustration in the owner's manual and make sure that only the frame areas are used. In addition, be especially careful that you do not damage the catalytic converter. Remember that various cross braces and supports on a lift can sometimes-contact low hanging parts of a car.
