Lifting and Jacking the Vehicle

Caution: To avoid any vehicle damage, serious personal injury or death, always use the jackstands to support the vehicle when lifting the vehicle with a jack.

Caution: To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed.


Notice: Perform the following steps before beginning any vehicle lifting or jacking procedure:

  ? Remove or secure all of the vehicle's contents in order to avoid any shifting or any movement that may occur during the vehicle lifting or jacking procedure.
  ? The lifting equipment or the jacking equipment weight rating must meet or exceed the weight of the vehicle and any vehicle contents.
  ? The lifting equipment or the jacking equipment must meet the operational standards of the lifting equipment or jacking equipment's manufacturer.
  ? Perform the vehicle lifting or jacking procedure on a clean, hard, dry, level surface.
  ? Perform the vehicle lifting or jacking procedure only at the identified lift points. DO NOT allow the lifting equipment or jacking equipment to contact any other vehicle components.
Failure to perform the previous steps could result in damage to the lifting equipment or the jacking equipment, the vehicle, and/or the vehicle's contents.


For lifting the vehicle, various lift points are recommended. Before you begin any lifting procedure, place the vehicle on a clean, hard, level surface. Verify that all the lifting equipment meets weight standards and is in good working order. Verify that all of the vehicle loads are equally distributed and secure. If you are only supporting the vehicle at the frame side rails, verify that the lifting equipment does not put too much stress on, or weaken, the frame side rails.

During hoisting, do NOT damage the fuel tanks, the exhaust system, or the underbody. :2:

Frame Contact Hoist

Front Hoist Pads



Important:
The front hoist pads must not contact the rocker panels, the front fenders, or the floor pan.


Position the front hoist pads under the front frame between the lower control arm and the frame pad.

Rear Hoist Pads



Important:
The rear hoist pads must not contact the body rocker panels or the floor pan.


Position the rear hoist pads under the rear spring, just behind the hanger.

Suspension Contact Hoist

Front Lift



Position the front lift under the outer edge of the front suspension lower control arms.

Rear Lift



Position the rear lift under the axle housing tubes on each side of the differential.

Do not damage the stabilizer bar. :2:

Jacking

When you are lifting a vehicle with a vehicle jack or a floor jack, block the wheels at the opposite end from which you are lifting. Use jack stands to provide additional support.

Under the Frame Rails




Important:
The floor jack pad must not contact rocker panel or the floor pan.


Position the floor jack pad under the frame rail pad.

Under the Rear Differential



Position the floor jack pad under the center of the rear axle differential.

Do not damage the establisher bar.

Under the Rear Spring Hanger



Position the jack under the rear spring hanger.

Jack Stands

When you support the vehicle with jack stands, place the jack stands under the frame, the front suspension crossmember, or the rear axle.
 
Tire and Wheel Removal and Installation

Tools Required

J 39544-KIT Complete Torque Socket Set

Caution: If penetrating oil gets on the vertical surfaces between the wheel and the rotor or drum it could cause the wheel to work loose as the vehicle is driven, resulting in loss of control and an injury accident.

Notice: Never use heat to loosen a tight wheel. It can shorten the life of the wheel, studs, or hub and bearing assemblies. Wheel nuts must be tightened in sequence and to the specified torque to avoid bending the wheel or rotor.

Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. In order to avoid expensive brake repairs, evenly tighten the wheel nuts to the proper torque specification.

Important: Removing wheels can be difficult because of foreign material or a tight fit between the wheel center hole and the hub or rotor. Excessive force, such as hammering on the wheel or tire, can cause damage. Slightly tapping the tire side wall with a rubber mallet is acceptable.

  1. Tighten all wheel nuts on the affected wheel.
  2. Loosen each wheel nut 2 turns.
  3. Rock the vehicle from side to side in order to loosen the wheel. If this does not loosen the wheel, rock the vehicle front to back applying quick hard jabs to the brake pedal to loosen the wheel.
  4. Repeat this procedure if the wheel does not break free.

Removal Procedure

  1. Raise the vehicle. Support the vehicle with suitable safety stands. Refer to Lifting and Jacking the Vehicle.
  2. Remove the wheel center cap.



  3. Remove the wheel nuts from the tire and wheel.
  4. Mark the location of the tire and wheel to the hub assembly.
  5. Remove the tire and wheel from the vehicle.
  6. Clean the wheel nuts, studs and the wheel and rotor mounting surfaces.

Installation Procedure

Caution: Before installing the wheels, remove any buildup of corrosion on the wheel mounting surface and brake drum or disc mounting surface by scraping and wire brushing. Installing wheels with poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This can cause a wheel to come off when the vehicle is moving, causing loss of control and possibly personal injury.

Notice: A torque wrench or J 39544 must be used to ensure that wheel nuts are tightened to specification. Never use lubricants or penetrating fluids on wheel stud, nuts, or mounting surfaces, as this can raise the actual torque on the nut without a corresponding torque reading on the torque wrench. Wheel nuts, studs, and mounting surfaces must be clean and dry. Failure to follow these instructions could result in wheel, nut, and/or stud damage.




  1. Install the tire and wheel. Align the locating mark of the tire and wheel to the hub.

     Notice: Refer to Fastener Notice.




    Important: Tighten the nuts evenly and alternately in order to avoid excessive runout.

  2. Install the wheel nuts.

     Tighten

     Tighten the wheel nuts as shown to 190 N?m (140 lb ft).

  3. Install the wheel center cap.
  4. Remove the safety stands.
  5. Lower the vehicle.
