Steering Column Replacement (Hydraulic)
Steering Column Replacement (Hydraulic)
Removal Procedure
1. Caution: Refer to Restraint System in Service Precautions.
Disable the SIR system.
Caution: Refer to Battery Disconnect in Service Precautions.
Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure.
Notice: Once the steering column is removed from the vehicle, the column is extremely susceptible to damage. Dropping the column assembly on the end could collapse the steering shaft or loosen the plastic injections, which maintain column rigidity. Leaning on the column assembly could cause the jacket to bend or deform. Any of the above damage could impair the columns collapsible design. Do NOT hammer on the end of the shaft, because hammering could loosen the plastic injections, which maintain column rigidity. If you need to remove the steering wheel, refer to the Steering Wheel Replacement procedure.
Important: In the event of a deployment, inspect the coil wire for any of the following signs of damage due to excessive heat:
^ Scorching
^ Melting
^ Other damage
Replace the coil, if necessary.
Important: The wheels on the vehicle must be straight ahead before disconnecting the steering column or intermediate shaft. Do NOT rotate the steering column after disconnecting the steering column or intermediate shaft. Doing so will cause the SIR coil assembly to become uncentered, which may cause damage to the coil assembly.
Remove the steering wheel.
2. Remove the SIR coil assembly.
3. Remove the multifunction turn signal.
4. Remove the multifunction turn signal switch housing.
5. Remove the steering column knee bolster.
6. Remove the steering column shaft pinch bolt from the intermediate steering shaft.
7. Important: Install tie straps (1) between the rake bracket assembly (2) and the base of the steering column to prevent jacket assembly pull-apart. The steering column rake lever MUST be in the LOCK (FULL UP) position during steering column removal and installation to ensure that the rake lever bracket remains rigid. Install a tie strap around the lever and the jacket assembly to keep the lever in the LOCK position. Do not bend the steering column energy absorbing straps located on the upper steering column mounting bracket.
Disconnect the steering column electrical connectors open the steering column wire harness retainer clip.
8. Important: DO NOT disconnect the adjustable brake pedal cable.
Remove the adjustable pedal bracket assembly and reposition leaving the brake pedal cable and motor attached, if vehicle is equipped with adjustable pedals.
9. Remove the upper steering column mounting bolts (1).
10. Remove the lower steering column mounting bolt.
11. Remove the steering column from the vehicle.
Installation Procedure
1. Important: Do not bend the steering column energy absorbing straps located on the upper steering column mounting bracket during installation.
Position the steering column in the vehicle.
2. Slide the lower end of the steering column shaft into the intermediate steering shaft.
3. Loosely install the lower steering column mounting bolt.
4. Loosely install the upper steering column mounting bolts (1).
5. Important: Do not bend the steering column energy absorbing straps located on the upper steering column mounting bracket during installation.
Align the energy absorbing straps with the bolt holes in the steering column. Loosely install the upper steering column bolts (1).
6. Caution: In order to ensure the intended function of the steering column in a vehicle during a crash and in order to avoid personal injury to the driver, perform the following:
^ Tighten the steering column lower fasteners before you tighten the steering column upper fasteners. Failure to do this can damage the steering column.
^ Tighten the steering column fasteners to the specified torque. Overtightening the upper steering column fasteners could affect the steering column collapse.
Notice: Refer to Fastener Notice in Service Precautions.
Tighten the steering column fasteners in the following sequence:
3. Tighten the lower bolt to 27 Nm (18 ft. lbs.).
4. Tighten the left side upper bolt to 27 Nm (18 ft. lbs.).
5. Tighten the right side upper bolt to 27 Nm (18 ft. lbs.).
7. Connect the steering column electrical connectors and close the wire harness retainer clip on the steering column.
8. Remove the tie strap (1)from from the steering column (2).Remove the wire strap from around the rake lever and the jacket assembly.
9. Install the adjustable pedal bracket assembly, if equipped with adjustable pedals.
10. Install the steering column knee bolster.
11. Install the multifunction turn signal switch housing.
12. Install the multifunction turn signal.
13. Install the SIR coil assembly.
14. Install the steering wheel.
15. Connect the negative battery cable.
16. Enable the SIR system.
17. Inspect all of the steering column components for correct operation.
