Q: How to Service and Repair the Air Bag Clockspring Assembly on GMC Jimmy?
A: Startprocedure of air bag clock spring assembly / spiral cable repairs by disabling the sir system. Start by removing the Steering Wheel followed by the tilt lever (if present) and then both upper and lower steering column trim covers. Pull the wire harness assembly from its wire harness strap after removing 3 wire harness straps from the wire harness assembly then disconnecting the wire harness strap from the upper tilt head assembly. Start by taking off the coil assembly retaining clip followed by the coil assembly and wave washer. Make sure all fasteners are properly installed before torque application because it will prevent damage to the components. Begin by setting the block tooth on the race and upper shaft assembly to 12 o'clock for sir coil assembly positioning. Double-check the assembly remains centered while installing the wave washer. The coil assembly loses its centered position when the steering column separates from the steering gear or if operators depress the centering spring during coil removal. Install the precentered coil assembly to the steering column then remove the centering tab so you can discard it. When installing the coil assembly use the projections from the canceling cam assembly outer ring to align it with the horn tower on the inner ring. You should gently pull the lower coil assembly wire to smooth out any kinks because any bends or kinks in the sir coil assembly wire will cause issues with the shaft lock mechanism. Embed the coil assembly retaining ring into the upper shaft assembly groove with complete seatment. First insert the wire harness assembly into the wire strap followed by installing the wire harness strap into the wire strap while placing the 3 wire harness straps from the wire harness assembly. Reinstallation should begin with the upper and lower steering column trim covers along with the tilt lever (if present) and Steering Wheel and the enables the sir system.
Q: How to Remove and Replace the Air Bag Clockspring Assembly on GMC Envoy?
A: The air bag clock spring assembly / spiral cable replacement operation requires disabling the sir system before proceeding. Begin with a center position tilt of the Steering Column before you remove the Steering Wheel from its column. The next step requires you to eliminate both the upper and bottom trim pieces. Check the Steering Column for damage caused by accidents when possible. Pad control enabled steering wheels require the entire inflatable restraint Steering Wheel module coil and wire harness assembly to be removed at once. The coil can be removed by itself when such removal technique is approved. Use a screwdriver to eliminate the wire harness strap alongside possible wire harness assembly detachment. Steer towards the removal of the Steering Wheel module coil after using snap ring pliers on the retaining ring. The installation of the wave washer occurs when required. Insert and position the wave washer carefully along the Steering Shaft assembly block tooth at the 12 o'clock direction. Installation of new inflatable restraint Steering Wheel modules must wait until final installation because their centering tab serves as a pre-installation organizer. Users must verify that their originally used coil maintains proper positioning before further installation steps. Guide the inflatable restraint Steering Wheel module coil to face the horn tower before sliding it onto the Steering Shaft assembly. Use snap ring pliers to install the retaining ring into the race and upper shaft assembly's groove. Then discard the centering tab but ensure the whole retaining ring is seated properly. Put the retaining ring into position using snap ring pliers. Whenever a Steering Wheel has pad control functions you need to add the wire harness assembly. Set the wire harness strap in place before you install upper and lower trim covers as well as the Steering Wheel onto its column. Finally, enable the sir system.
Q: How to Remove and Replace the Air Bag Clockspring Assembly on GMC Sierra 1500?
A: Prior to air bag clock spring assembly / spiral cable removal and replacement secure the Steering Wheel with a Steering Column anti-rotation pin (J 42640) or column lock or safety strap to avoid sir system damage. Follow these procedures when working on the Steering Column and intermediate shaft(s) but avoid moving the front tires or rotating the Steering Wheel because that could un-center the sir coil assembly. Check wheel direction alignment and verify the anti-rotation pin (J 42640) is present or the ignition switch is in the lock position before removing the Steering Wheel, then the Steering Column shroud, followed by electrical connector disconnection. First remove the inflatable restraint Steering Wheel module coil retaining ring before extracting the inflatable restraint Steering Wheel module coil. The procedure calls for discarding any previous coil when replacing it. First install the sir coil assembly into the proper central position before removing the centering tab after complete installation. The installation procedure for an existing coil requires proper coil alignment. Lay the inflatable restraint Steering Wheel module coil over the horn tower on the turn signal switch cancel cam before sliding it onto the Steering Shaft and getting the new retaining ring perfectly seated in the Steering Shaft groove. Replace the centering tab from your new steering coil after you reconnect electrical connections and install both the Steering Column shroud followed by the Steering Wheel. As the last step, remove the anti-rotation pin (J 42640).
