Vehicle Lifting: Description and Operation

JACKING

WARNING:
- The electrical power to the air suspension system must be shut off prior to hoisting or jacking an air suspension equipped vehicle. Failure to do so may result in unexpected inflation or deflation of the air springs which may result in shifting of the vehicle during these operations. Failure to follow these instructions may result in personal injury.
- Do not run the engine when jacking the vehicle. The wheels contacting the ground could cause the vehicle to move.
- Support the vehicle prior to carrying out any procedure requiring the vehicle to be jacked off the ground.
- Make sure the jack and jack stands are correctly located to prevent the vehicle from falling.
- Wheel chocks should be used to prevent the vehicle from rolling and falling off the jack.

CAUTION:
- Never use a halfshaft as a lifting point.
- If equipped with retractable running board, disable the system through the instrument cluster controls.

Disable the air suspension system. Refer to Electronic Level Control.

Jacking Points - Front







The front jacking point is indicated by an arrow cutout in the frame, located behind the front tire and wheel assembly.

After the vehicle has been lowered, enable the air suspension system. Refer to Electronic Level Control.

Jacking Points - Rear







CAUTION: Do not use the differential housing as a lift point. Leaks or damage to the rear axle cover and adjoining differential housing surface can occur if a floor jack or any lifting device is allowed to contact the cover at any point where the cover joins the housing.







CAUTION: Do not use the rear control arms as a lifting point.

The rear jacking point is indicated by an arrow cutout in the frame, located in front of the rear tire and wheel assembly.

After the vehicle has been lowered, enable the air suspension system. Refer to Electronic Level Control.
