Steering Column Replacement Floor Shift

Tools Required

    • J 42640 Steering Column Antirotation Pin
    • J 41352 Modular Column Holding Fixture

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.

  1. Disable the SIR system. Refer to SIR Disabling and Enabling in SIR.
