J 42640 Steering Column Lock Pin

Removal Procedure

    Caution: Refer to SIR Caution in the Preface section.

    Notice: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly to become uncentered, which may cause damage to the coil assembly.

    Notice: Once the steering column is removed from the car, the column is extremely susceptible to damage. Dropping the column on its end could collapse the steering shaft or loosen the plastic injections which maintain column rigidity. Leaning on the column could cause the jacket to bend or deform. Any of the above damage could impair the column's collapsible design. If it is necessary to remove the steering wheel, use only the specified steering wheel puller. Under no conditions should the end of the shaft be hammered upon as hammering could loosen plastic injections which maintain column rigidity.

    Notice: The steering column should never be supported only by the lower support bracket. Damage to the lower support could result.

Installation Procedure


    Object Number: 141935  Size: SH

    Caution: In order to ensure the intended function of the steering column in a vehicle during a crash and in order to avoid personal injury to the driver, perform the following:

       • Tighten the steering column lower fasteners before you tighten the steering column upper fasteners. Failure to do this can damage the steering column.
       • Tighten the steering column fasteners to the specified torque. Overtightening the upper steering column fasteners could affect the steering column collapse.

    Notice: If a service replacement steering column is being installed, do not remove the anti-rotation pin until after the steering column has been connected to the steering gear. Removing the anti-rotation pin before the steering column is connected to the steering gear may damage the SIR coil assembly.

    Important: 

       • When installing the steering column, install the fasteners needed for completing each step of the installation. DO NOT tighten the fasteners until the procedure tells you to do so.
       • In order to ensure that the column absorbs energy correctly, use only the specified screws, bolts, and nuts. Tighten the components to the specified torque.

  1. Install the steering column to the vehicle.
  2. Install the lower support bracket studs mounting nuts (1).
