Just a note of mention, this sensor will not exhibit a symptom of shimmy. What usually happens when a sensor is failing is the steering effort will vary when rotating. It could be somewhat stiff, or normal, and all of a sudden get real easy, or vice versa.

Steering Wheel Position Sensor or Steering Shaft Lower Bearing Replacement
Removal Procedure

Set the front wheels in the straight-ahead position.
Set the steering wheel in the LOCKED position.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

For Vehicles equipped with OnStar (UE1) with Back Up Battery:

The Back Up Battery is a redundant power supply to allow limited OnStar functionality in the event of a main vehicle battery power disruption to the VCIM (OnStar module). Do not disconnect the main vehicle battery or remove the OnStar fuse with the ignition key in any position other than OFF. Retained accessory power (RAP) should be allowed to time out or be disabled (simply opening the driver door should disable RAP) before disconnecting power. Disconnecting power to the OnStar module in any way while the ignition is On or with RAP activated may cause activation of the OnStar Back-Up Battery (BUB) system and will discharge and permanently damage the back-up battery. Once the Back-Up Battery is activated it will stay on until it has completely discharged. The BUB is not rechargeable and once activated the BUB must be replaced.

Disconnect the negative battery cable.
Disable the supplemental inflatable restraint (SIR). Refer to Disabling the SIR System in SIR.
Remove the nut and the bolt from the upper to the lower steering shaft connection.
Slide the lower shaft down.

Remove the position sensor connector by using a suitable tool in order to pull the connector down around the right side of the steering column for accessibility.
Important: Do not apply force to the sensor and the bearing in a sideways direction.

Remove the position sensor and bearing assembly from the steering column jacket by pulling the assembly straight out.
Remove the position sensor from the clips in the bearing assembly.
Installation Procedure

Install the position sensor into the bearing assembly.
Install the bearing into the steering column jacket.
2.1. Align the notches on the bearing and the column jacket.

Important: Do not apply force to the sensor and the bearing in a sideways direction.

2.2. Seat the bearing fulling into the jacket.

Connect the position sensor connector.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Install the bolt and the nut to the upper end of the shaft.
Tighten the nut to 62 N m (46 lb ft).

Connect the negative battery cable.
Enable the SIR system. Refer to Enabling the SIR System in SIR.
