Warning!This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:
• Air bag deployment
• Personal injury
• Unnecessary SIR system repairs
In order to avoid the above conditions, observe the following guidelines: • Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring.
• If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System.

1. Disable the SIR System. Refer to Disabling the SIR System in SIR.

Hope this helps. Be very careful where airbag is involved.

Steering Column Replacement Hope this helps?

Tools Required

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

Removal Procedure

Warning! Refer to SIR Caution in Cautions and Notices.
Caution! 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.
Caution! 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 Zone 3 in SIR.




2. Insert J 42640 into the steering column access hole in order to lock the steering column. This will maintain the correct orientation.
3. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.




4. Remove the intermediate shaft lower pinch bolt.
5. Remove the intermediate shaft from the steering gear.
6. Lower the vehicle.




7. Remove the knee bolster. Refer to Bracket Replacement - Knee Bolster in Instrument Panel, Gages and Console.
8. Disconnect the steering column wiring harness connector from the main body wiring harness.
9. Disconnect the shift lever cable from the linear shift assembly.




10. Remove the shift cable retaining clip.




11. Press the shift cable tabs (1) together and remove the shift cable (2) from the steering column.



Caution! The steering column should never be supported only by the lower support bracket. Damage to the lower support could result.
Important Stabilize the studs in order to remove the nuts securing the steering column to the instrument panel.

12. Support the column.




13. Remove the lower steering column retaining nuts.
14. Remove the upper steering column retaining nuts.
Important Discard the clips at the upper steering column support, if equipped. These clips are for assembly plant usage only.

15. Remove the steering column from the vehicle.
16. Install the steering column into J 41352 .

CAUTION
The Supplemental Inflatable Restraint (SIR) system must be disarmed before working around the steering column. Failure to do may cause accidental deployment of the air bag, resulting in unnecessary SIR system repairs and/or personal injury.

1. Disconnect the negative battery cable.
2. If equipped, disable the SIR system.
3. Remove the steering column.
4. The ignition switch is located at the base of the steering column. Disconnect the vehicle wire harness from the ignition switch.
5. Unfasten the mounting screws, then remove the ignition switch assembly. To install: WARNING
   When fasteners are removed, always reinstall them at the same location from which they were removed. If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct part number is not available, a fastener of equal size and strength (or stronger) may be used. Fasteners that are to be reused, and those requiring thread locking compound will be called out. The correct torque value must be used when installing fasteners that require it. If the above conditions are not followed, parts or system damage could result.
