Steering Column, Green Line

Steer away from harming the Steering Column following removal because dropping it can cause the Steering Shaft to collapse along with damage to the plastic injections which stabilize column rigidity. Additionally, leaning on the assembly may deform the collapsible jacket leading to its compromised design. The use of hammers to strike the end of the shaft must be avoided because it could release the plastic injections. The correct step-by-step procedure exists for removing the Steering Wheel. Start the process by installing a scan tool while having the ignition turned on with the engine set to off. Place the Steering Wheel in its centered position before removing all hands and objects from it and relaxing the suspension system to prevent uneven steering system forces. To check the Steering Shaft torque parameter use the scan tool and power steering system data displays list to monitor its data between 1 nm (0.7 ft. Lbs). The replacement of the Steering Column assembly should be performed when the torque data parameter exceeds this reference value. To prevent failure in the coil wire inspect for thermal damages such as burning or melting during deployment. Replacing the coil will be necessary if any damage is present. Before rotating the shaft the inflatable restraint coil assembly needs to be detached from the Steering Column to remain free-hanging because this prevents damage. Visual examination of the Steering Shaft must be performed to check for sheared injected plastic materials because such damage requires replacing the complete Steering Column system. A damaged or misaligned Steering Column must be assumed after accidents that caused frame damage or major body or sheet metal damage or when the Steering Column was struck or when supplemental inflatable restraint systems deployed. You should perform the proper service approach before changing the Steering Column.
