Steering Wheel Position Sensor or Steering Shaft Lower Bearing

Steering Wheel Position Sensor or Steering Shaft Lower Bearing Replacement

Tools Required

- J 42640 Steering Column Anti-Rotation Pin

Removal Procedure






Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling Service and Repair. Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.

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

Notice: With wheels of the vehicle facing straight ahead, secure the steering wheel utilizing steering column anti-rotation pin, steering column lock, or 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(s)
- The steering gear
After disconnecting these components, do not rotate the steering wheel or move the front tires and wheels. Failure to follow this procedure may cause the SIR coil assembly to become un-centered and cause possible damage to the SIR coil. If you think the SIR coil has became un-centered, refer to your specific SIR coil's centering procedure to re-center SIR Coil.

2. Lock the steering column through the access hole in the lower trim cover using J 42640.






Important: A new sensor must come with a pin installed. If pin is not installed, return and reorder sensor. Do not apply force to the sensor and the bearing assembly in a sideways direction.

3. Remove the steering column from the vehicle. Refer to Steering Column Replacement Steering Column.
4. Remove the sensor connector by using a suitable tool in order to pull the connector down around the right side of the steering column for accessibility.
5. Remove the sensor retainer from the steering shaft.






Important: When reusing the sensor (1) you must install a pin into the sensor before it is removed from the steering shaft. By not installing a pin into the sensor it will cause the sensor to lose its centering position and must be discarded. Pin diameter must be in the range of 1-2 mm. Do not remove the bearing adapter (3).

6. If reusing the sensor (1), remove the position sensor by pulling the sensor straight out from the bearing adapter (3) until the sensor is almost off the steering shaft (2). Install a pin into the sensor before removing from the steering shaft (2). Do not remove the pin until the sensor is re-installed.
7. If replacing the sensor (1), remove the sensor by pulling the sensor straight out from the bearing adapter (3) and off the steering shaft.

Installation Procedure






Important: Do not apply force to the sensor (1) or the bearing adapter (3) in a sideways direction.

1. If reusing the sensor, with the pin still installed, align the sensor onto the steering shaft (2) and into the bearing adapter (3).

Important: If installing a new sensor the sensor will come precentered. Do not remove the pin until installation is complete.

2. Install the sensor onto the steering shaft (2) and into the bearing adapter (3).






3. The sensor must be set to approximately 3 mm gap between the sensor and the bearing adapter.
4. Install the sensor connector.
5. Remove the pin from the sensor.
6. Install the sensor retainer onto the steering shaft.






7. Install the steering column to the vehicle. Refer to Steering Column Replacement Steering Column.
8. Remove J 42640 from the steering column.
9. Enable the SIR system. Refer to SIR Disabling and Enabling Service and Repair.
