  Q: How to service the Air Bag Clockspring Assembly / Spiral Cable on GMC C3500?

  A: As an initial step to service the air bag clock spring assembly you must disable the sir system. Disassemble by removing the Steering Wheel assembly along with the tilt lever (if present) followed by removing both upper and lower shrouds. Pop the wire harness assembly off the wire harness strap while extracting its 3 wire harness straps and upper tilt head assembly wire harness strap. After removing the air bag clock spring retaining clip you must remove the air bag clock spring and the wave washer. Before adding torque to the fasteners during installation verify that they are fully inserted because unsuitable force application could break the components. After installing the wave washer check that the air bag clock spring stays in the center position because both a detached Steering Column from the steering gear and a compressed centering spring may cause misalignment. Place the block tooth of the race and upper shaft assembly at the 12 o'clock location before installing the pre-centered air bag clock spring onto the Steering Column and throwing out the centering tab. Check the lower air bag clock spring wire for kinks by pulling it gently until any kinks straighten but watch out for any bends which may impact the shaft lock mechanism. Use the horn tower on the canceling cam assembly inner ring and the projections on the outer ring to guide air bag clock spring installation. Secure the air bag clock spring retaining ring to its designated groove on the upper shaft assembly. Afterwards, pop the wire harness assembly into the wire strap before installing the wire harness strap to the upper tilt head assembly. Place the multi-function switch lever assembly and bolt after reinstalling the 3 wire harness straps from the wire harness assembly. Complete the installation by putting on upper and lower shrouds and tilt lever (if installed) before enabling the sir system.
