GMC campaign no 72-c-4. Possibility that undersized pinch bolt was installedin lower yoke which connects upper and lower steering shafts possibly allowingloss of clamp load. If loose clamp bolt condition exists, bolt could fall outand allow upper universal joint andlower steering shaft to become disconnectedresulting in loss of steering control. (correct by inspecting and replacingwithnew bolt where necessary. )
