ON CERTAIN VEHICLES, THE ENDSTOP FOR THE SECONDARY CAB LOCK HOOK MAY EXPERIENCE ABNORMAL WEAR. THIS CAN PREVENT THE HOOK AND LATCHING BRACKET FROM ENGAGING WHEN THE CAB IS POWERED.
Manufacturer remedy
THE DEALER WILL INSTALL A GUIDE FOR THE SECONDARY CAB LOCK HOOK, AND REPLACE EXISTING HOOK WITH A MODIFIED VERSION FREE OF CHARGE.
OPERATION UNDER EXTREME CONDITIONS OF HIGH HUMIDITY, SALT AND DIRT CAN CAUSE RUSTING OF THE SPLINED SECTION OF THE UPPER STEERING SHAFT. THIS CAUSES INCREASED STRESSES BETWEEN THE STEERING COLUMN UNIVERSAL JOINT CONNECTION AND THE INPUT SHAFT OF THE STEERING GEAR. CONTINUED OPERATION UNDER THESE CONDITIONS COULD RESULT IN UNACCEPTABLE MOTION OF THE LINKAGES.
Manufacturer remedy
ALL AFFECTED VEHICLES WILL BE EQUIPPED WITH A GREASE FITTING ON THE SPLINED SECTION OF THE UPPER SIDE OF THE UNIVERSAL JOINT.
