While removal of the steering wheel is not usually required, it makes the job much easier.

  1. Remove the wiring harness bands or clips. Disconnect the ignition switch harness.
  2.  
  3. If the ignition switch (electrical part) can be removed from the lock, remove it. Older vehicles use one-piece units.
  4.  
  5. The installation bolts have no head (they were broken off during installation as a theft deterrent); use a hacksaw blade to cut a groove into the head of the special mounting bolts. Use a screwdriver placed in the new groove to remove the bolts.
  6.  
  7. Remove the lock assembly from the steering column.
  8.  

To install:
  1. With the key inserted in the new lock, install the lock assembly to the steering column and hand-tighten new bolts. Turn the key from time to time as the bolts are tightened, making sure the key does not bind.
  2.  
  3. Once the lock is in place and confirmed in working order, use a socket wrench to evenly tighten the bolts. Again check the key operation during the tightening. Continue tightening the bolts until the heads break off.
  4.  
  5. Connect the switch if it was removed from the lock assembly.
  6.  
  7. Connect the wiring harness and check the assembly for proper operation.
  8.  
  9. Reinstall or connect any wiring bands, clips or retainers which were loosened. It is important that the wiring be correctly contained and out of the way of any moving parts.
  10.  
  11. Install the upper and lower column covers.
  12.  
  13. Install the steering wheel if it was removed.
  14.  
  15. Connect the negative battery cable.
