The issue
Certain heavy-duty trucks equipped with (IROS) rear air suspensions. During assembly, four bolts and nuts holding the main support member bushing bar pins to the main support member hangers were incorrectly tightened. The nuts could work loose or fall off allowing the bolts to fatigue and fail the connection between a main support member bushing and a main support member frame hanger. Separation of the main support member assembly from the frame mounted hanger bracket could result increasing the risk of sudden loss of control of the vehicle. Correction: Dealers will install four new nuts and bolts and tighten to specification.
Description (français)
Vise certains poids lourds équipés de la suspension pneumatique IROS à l'arrière. Au cours du montage, quatre boulons et quatre écrous qui fixent les tiges de guidage du support principal de la suspension aux fixations du support principal n'ont pas été suffisamment serrés. Les écrous peuvent se desserrer et tomber, entraînant éventuellement la rupture par fatigue des boulons et le bris de la connexion entre la tige et la fixation du support principal, ce qui pourrait provoquer une perte de contrôle et causer un accident. Correction : Les concessionnaires devront poser et serrer au couple prévu quatre boulons et quatre écrous neufs.
