On the involved vehicles the floorboard opening and the steering column seal bracket do not have sufficient clearance to allow the shaft to turn freely. This causes the pinch bolt to bind or lock against the seal bracket.
The hole in the floorboard will be enlarged to allow sufficient clearance of the steering column u-joint pinch bolt, and a new bracket and lamp will be installed at no charge to owner.
Vehicle description: fire fighting equipment chassis equipped with sgp48steering gears. System: steering; steering column shaft u-joint clearances. Consequences of defect: there will be little or no wheel return; loss ofsteering control without prior warning could result in an accident.
