The jacking information from the CT4 service manual says:
Frame Contact Lift:
The vehicle should be lifted so that the hoist pads and or lift arms do not contact the rocker panel molding. The hoist pad must be located in the designated area. In the front location, place the lift pads on the rocker outer panel weld flange. In the rear location, place the lift pads on the rocker outer panel rear cradle brace. Care should be taken to ensure the hoist pad is inside the rocker panel molding cut out area (notch) to prevent damage to the vehicle.
Front Lift Pads
View attachment 17802
When lifting the vehicle with a frame-contact lift, position the pad as close as possible to the rocker molding cutout.
Rear Lift Pads
View attachment 17803
When lifting the vehicle with a frame-contact lift, cover the inner and outer edges of the rear suspension bracket (arrow). Use the cutout in the rocker molding to correctly position the pad for/aft. If you need to remove the rear suspension bracket, place a jack stand under area X. Raise the jack stand high enough to free the hoist pad from the rear suspension bracket for service.
Vehicle Jacking:
Caution: When you are jacking the vehicle at the front locations, be certain that the jack or the jack lift pad does not contact the front fascia, front fascia air dam, or the front fenders. If such contact occurs, vehicle damage may result. When jacking at selected front locations additional clearance may be required for the jacking points.
Note: When you are lifting a vehicle with a service jack, block the wheels at the opposite end from which you are lifting. Use jack stands to provide additional support.
