Vehicle Lifting: Service and Repair

WARNING: ON VEHICLES EQUIPPED WITH AIR SUSPENSION, THE ELECTRICAL POWER SUPPLY TO THE AIR SUSPENSION SYSTEM MUST BE SHUT OFF PRIOR TO HOISTING THE VEHICLE. THIS CAN BE ACCOMPLISHED BY DISCONNECTING THE BATTERY OR TURNING OFF THE POWER SWITCH LOCATED IN THE LUGGAGE COMPARTMENT ON THE RH SIDE. FAILURE TO DO SO MAY RESULT IN UNEXPECTED INFLATION OR DEFLATION OF THE REAR SPRINGS WHICH MAY RESULT IN SHIFTING OF THE VEHICLE DURING THESE OPERATIONS.

CAUTION: Do not allow the hoist adapters to contact the steering linkage, suspension arms, stabilizer bar, or to compress the lower suspension arm stabilizer bar insulators. Damage to suspension, exhaust or steering linkage components may occur if care is not exercised when positioning the hoist adapters of two-post hoists prior to lifting the vehicle.

If a two-post hoist is used to lift a vehicle, place the adapters under the front suspension lower arms.

Hoist, Drive On
To prevent possible damage to the underbody, do not drive the vehicle onto the drive-on hoist without first checking for possible interference between the upright flanges of the hoist rails and the underbody. If interference exists, the hoist flanges should be modified as necessary and the approach ramps built up to provide the necessary clearance.

Hoist, Frame Contact

WARNING: WHEN HOISTING AT LIFT POINTS, ESPECIALLY FRONT LIFT POINTS, BE CAREFUL OF CONTACTING BRAKE LINES AND FUEL LINES.

CAUTION:
- All four contact points must contact the adapters.
- Never use the differential housing as a lift point (applies to all rear wheel drive vehicles).

NOTE: Before hoisting the vehicle, verify that there is sufficient clearance between the hoist and the exhaust system components.

Vehicle Lift Points:

On frame contact hoists, adapters are necessary to lift the vehicle. The adapters must be placed at four contact points. Position the adapters so they are centered on the adapter contact area.

Exercise care when hoisting vehicles equipped with catalytic converter(s). On vehicles so equipped, verify necessary clearance between hoist and exhaust system components before energizing hoist.

Vehicles with unitized body-frame construction require special precautions and procedures when the vehicle is jacked up or hoisted. In some cases, special hoist adapters must be used as recommended by specific hoist manufacturers.

Hoist, Twin Post
To ensure safe hoisting, the front post adapters must be positioned carefully to contact the center of the lower suspension arms.

Jack, Floor

WARNING: NEVER RUN THE ENGINE WITH ONE WHEEL OFF THE GROUND.

CAUTION:
- The service jack provided with the vehicle is only intended to be used in an emergency for changing a deflated tire. Never use the service jack to hoist the vehicle for any other service. Refer to the Owner Guide when using the jack supplied with the vehicle.
- Do not attempt to use jack pressure on either the front bumper or the rear bumper of any unitized vehicle.
- Care must be exercised not to contact the steering linkage or to compress the lower suspension arm stabilizer bar insulators.
- Never use the differential housing as a lift point.

When using a floor jack, the vehicle may be raised at several locations. The front of the vehicle may be lifted by positioning the floor jack under the center of the No. 2 crossmember. The front, as well as either side of the rear end, may be lifted by positioning the floor jack under the rocker flange at the contact points used for the service jack supplied with the vehicle.

Position jacks under the rear axle housing tubes between the suspension arm brackets and the differential housing. Do not place jacks under the suspension arm brackets.
