Defect, Vehicles, Dealer and Owner Information

DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1988 C/K 15-25 model trucks built at Ft. Wayne. One or both of the outer tie rod nuts may be loose and not crimped. A loss of one or both of these nuts could lead to the outer tie rod(s) disengaging from the steering knuckle resulting in a possible loss of steering control which could lead to a vehicle crash without prior warning.
To prevent this condition from occurring it will be necessary to inspect the outer tie rod nuts for crimping on all involved vehicles. If a non-crimped nut is found, the tie rod and knuckle are to be replaced and the toe-in set.
