REMOVAL & INSTALLATION



See Figures 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10

For 1974-76 models equipped with A.C.R.S. perform the special procedure following, prior to removing steering wheel.

Special Procedure for Cars with A.C.R.S.

Some 1974-76 models have an Air Cushion Restraint System (A.C.R.S). One of the elements of this complex system is an air cushion module. The steering wheel can be removed in the manner described in this section after the module has been removed.

To remove the module:
  1. Turn the ignition lock to the LOCK position.
  2.  
  3. Disconnect the battery ground cable and tape the end to prevent any possibility of a complete circuit.
  4.  
  5. Remove the 4 module-to-steering wheel screws. A special tool is available to do this.
  6.  
  7. Lift up the module and disconnect the horn wire.
  8.  
  9. Disconnect the module wire connector. A special tool is available to do this, too.
  10.  

To install the module:
  1. Hold the module with the emblem in the lower right corner.
  2.  
  3. Loop the air cushion harness clockwise from the 11 o'clock position to the 6 o'clock position.
  4.  
  5. Install the module connector by pushing it onto the column circuit firmly. Check that it is fully seated.
  6.  
  7. Install the horn wire.
  8.  
  9. Position the module, making sure that the wiring is still in place, and install the 4 screws. Torque them to 40 inch lbs. (4.5 Nm).
  10.  
  11. Reconnect the battery ground cable.
  12.  
  13. Turn the ignition lock to any position other than LOCK and check that the restraint indicator light operates correctly.
  14.  


CAUTION
The driver air cushion module should always be carried with the vinyl cover away from all parts of one's body and should always be laid on a flat surface with the vinyl side up. This is necessary so that a free space is provided to allow the air cushion to expand in case of accidental deployment. Do not attempt to repair any portion of the module. The module must be serviced as a unit. Attempting repairs such as soldering wires, changing covers, etc. may cause accidental inflation or impair operation of the driver module and cause serious injury.Do not dispose of a module in any way. The highly flammable material in the module can cause serious burns if ignited. Modules must be exchanged at an authorized dealer's parts department.

  3. Remove the center pad assembly, either by removing the screws or by gently prying the pad off. Lift up on the pad and disconnect the horn wire by pushing in on the insulator and turning counterclockwise.
  4.  
  5. Remove the steering wheel nut retainer and attaching nut. Using a puller, remove the steering wheel.
  6.  

To install:
  1. Align the marks on the wheel hub to the marks on the steering shaft.
  2.  
  3. Install the steering wheel, retainer and nut, then torque the nut to 30 ft. lbs. (41 Nm).
  4.  

When the mark on the steering wheel hub and the steering shaft are lined up, the wheel spokes should be horizontal as the car is driven straight ahead. If they are not horizontal it may be necessary to adjust the tie rod ends until the steering wheel is properly aligned.

  1. Install the horn wire in the cam tower, push in and turn clockwise. Align the pad assembly into position and either press into place or install the screws. Connect the negative battery cable.
