INTERMEDIATE STEERING SHAFT BOOT REPLACEMENT

Removal Procedure

1. Turn the steering wheel to the straight forward position and lock the steering column.

CAUTION: 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:

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 become un-centered, refer to your specific SIR coil's centering procedure to re-center SIR Coil.

2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.

3. Remove the left front tire and wheel assembly. Refer to Tire and Wheel Removal and Installation.

4. Disengage the intermediate steering shaft boot from the steering gear and from the intermediate steering shaft upper seal.

5. Remove the intermediate steering shaft lower bolt (1). Discard the bolt.

STEERING COLUMN ACCIDENT DAMAGE INSPECTION

Inspection Procedure

1. Inspect the capsules on the steering column bracket assembly. Verify that the capsules are seated securely in the bracket slots and inspect the capsules for any loose conditions when pushed or pulled by hand. If the capsules are not secure, perform one of the following procedures:

TELESCOPING STEERING COLUMN CALIBRATION

Tilt/Telescoping Soft Stops

After replacement of the memory seat module (MSM), it is necessary to program the tilt/telescoping soft stops.

Each soft stop is a programmable end of travel that is set approximately 1.3 cm (0.5 in) from the mechanical end of travel. The steering column has a soft stop set at each end of the telescoping in/out and tilt up/down movement. The system uses soft stops to prevent wear on the system by ensuring that the steering column movement stops before it reaches its mechanical end of travel in any direction. The soft stops are initially programmed at the factory. The stop positions may be reprogrammed, which is necessary any time the MSM, the tilt actuator or telescope actuators replaced, as described in the following procedure.

Tilt/Telescoping Soft Stop Programming Procedure

  1. Turn ON the ignition, with the engine OFF.
  2. Connect a scan tool to the vehicle.
  3. Select Model Year.
  4. Select LD Truck.
  5. Select Brand.
