Possibility the bolt which clamps the upper universal joint yoke to the lower steering shaft may not have been properly tightened and may have been the wrong type and could loosen. A loose clamp bolt could fall out and allow the upperuniversal joint and lower steering shaft to become disconnected, re- sulting in loss of steering control. (correct by replacing the upper universal joint yoke clamp bolt. )
