Callout Component Name
NOTE: Secure the steering wheel utilizing a strap to prevent rotation. Locking of the steering column will prevent damage and a possible malfunction of the SIR system. The steering wheel must be secured in position before disconnecting the following components:
  • The steering column
  • The intermediate shaft
  • The steering gear

After disconnecting these components, do not move the front tires and wheels. Failure to follow these procedures may cause improper alignment of some components during installation and result in possible damage to the SIR coil.
Preliminary Procedure: Turn the wheels of the vehicle straight ahead and install anti-rotation pin J 42640  into the steering column shroud access hole.
