The issue
NOTE: 1971 TO 1987 TRUCKS WITH NEWAY AIR RIDE DRIVE AXLE SUSPENSION. THE CHANNEL TYPE CROSSMEMBER INSTALLED WITH THE SUSPENSION CAN BE OVERSTRESSED AND CAN FAIL. THE BROKEN CROSSMEMBER CAN PROTRUDE ABOVE THE TOP OF THE FRAME AND INTERFERE WITH THE TRAILER CHASSIS COMPONENTS. THIS COULD ADVERSELY AFFECT HANDLING WHEN TURNING. ALSO, A COMPLETELY SEPARATED CROSSMEMBER WITH ATTACHED HEIGHT CONTROL VALVES COULD AFFECT THE HEIGHT OF THE SUSPENSION AIR SPRINGS. THE RESULTING LEAN COULD CAUSE LOSS OF CONTROL.
Description (français)
NOTA: véhicules équipés de la suspension pneumatique Neway sur l'essieu moteur. L'entretoise en U de la suspension Neway peut subir des contraintes excessives. Elle peut alors faire saillie par rapport au dessus du cadre et nuire à certains éléments du châssis dans les virages. Par ailleurs, si l'entretoise se détache avec les soupapes de commande de hauteur, la chute de pression dans la suspension pneumatique peut altérer le comportement routier du véhicule au point de provoquer un accident.
