Removal And Installation: CLOCKSPRING
REMOVAL
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.
Always turn the steering wheel until the front wheels are in the straight-ahead position. Then, prior to disconnecting the steering column from the steering gear, lock the steering wheel to the steering column. If clockspring centering has been compromised for ANY reason, the entire Steering Column Control Module (SCCM) and clockspring unit MUST be replaced with a new unit.
- Place the front wheels in the straight ahead position and inhibit the steering column shaft from rotation.
- Disconnect and isolate the negative battery cable.
- Remove the steering wheel from the upper steering column. Refer to WHEEL, STEERING, REMOVAL AND INSTALLATION .
- If the removed clockspring and stalk unit is to be reused, be certain that the spring-activated clockspring locking ring has extended upward following steering wheel removal to lock the clockspring rotor to the clockspring case and maintain clockspring centering until the steering wheel is reinstalled on the steering column. Do not manually compress the clockspring locking ring while the stalk unit is removed from the steering column as this may result in the loss of clockspring centering. Optionally, secure the clockspring rotor to the clockspring case with adhesive tape. If clockspring centering is not maintained, the entire clockspring and stalk unit must be replaced with a new unit before the steering wheel is installed.
- Move the steering column to the fully lowered (down) position.
- Remove the upper shroud from the steering column. Refer to SHROUD, REMOVAL AND INSTALLATION .
- Remove the lower shroud from the steering column. Refer to SHROUD, REMOVAL AND INSTALLATION .
- Disconnect the clockspring wire harness connectors from the clockspring.
1 - Clamp Screw 2 - Wire Harness Connectors - Loosen the band clamp screw.
- Remove the clockspring.
INSTALLATION
Follow the removal procedure in reverse for general reassembly of the components on the vehicle. The steps listed below are calling out specific procedures that should be followed during installation.

- A service replacement clockspring and stalk unit is shipped with the clockspring pre-centered and with a molded plastic locking pin installed. This locking pin should not be removed until the clockspring and stalk unit has been installed on the steering column.
- Position the clockspring to the top of the steering column and engage it to the steering column tab.
1 - Steering Column Tab - Tighten the band clamp screw to the proper torque specifications. Refer to TORQUE SPECIFICATIONS .
- Align the tires of the vehicle, connect the scan tool and perform the Steering Angle Sensor Calibration Routine. Refer to EPS - STEERING ANGLE CALIBRATION PROCEDURE
. The following preconditions are required before running the routine:
- Correct the vehicle tire pressure.
- Perform the wheel alignment standard procedure. Refer to WHEEL ALIGNMENT .
- Place the steering wheel in the straight ahead position +/- 1.5° from the straight position.
- Car is sitting on its wheels.
- Only the driver should be sitting in the vehicle.
- Vehicle stationary and no torque is applied on the steering wheel.
