DEFECT #2 - WHEELS:CAP/COVER/HUB
Posted on: 1979-10-12
Description
The aluminum hubs on the involved vehicles may be subject to failure due to cracks that may develop around the base of the inner bearing cup. These cracks may spread around the barrel of the hub and may lead to fracture and hub separation. The separated hub is retained on the axle spindle by the wheel bearing adjusting nut.
Consequence
Corrective Action
Dealer will inspect and will replace front axle aluminum hubs with steel ones, without charge.
Notes
Vehicle description: heavy trucks.system: wheels; aluminum hubs.consequences of defect: continued vehicle operation following hub failure maylead to brake lock-up, tire blow-out, or disengagement of the hub, tire, andwheel assembly from the vehicle. Loss of vehicle control and an accident mayresult in each case.note: an audible sound may be heard at the instant hub separation occurs. Untilreplacement hubs are obtained, hubs should be visually checked for the presenceof cracks. If cracks are found, the vehicle should immediately be removed fromservice and the dealer notified.
DEFECT #3 - TRAILER HITCHES:FIFTH WHEEL ASSEMBLY
Posted on: 1979-10-12
Description
On the involved vehicles, the mounting tabs used to mount the fifth wheel assembly to the chassis in place of the normal continuous angle construction could crack. These cracks can develop in the areas where the tabs are welded to the side of the fifth wheel assembly. If these cracks go undetected, the fifth wheel could eventually separate from the chassis.
Consequence
Corrective Action
Dealer will modify the fifth wheel mounting without charge to owner.
Notes
Vehicle description: heavy truck-tractors.system: structure; fifth wheel assembly.consequences of defect: separation could result in trailer disconnection whichcould in turn cause a vehicle accident and personal injuries.note: the vehicle should be visually inspected for cracks to reduce thepossibility of failure prior to obtaining the required fifth wheelmodification.
DEFECT #4 - STRUCTURE
Posted on: 1979-10-12
Description
Consequence
Corrective Action
Notes
Truck tractor.possibility that cab steps can develop cracks at the supportbrace which can eventually result in failure.if this condition exists, thesteps will be forced inboard when stepped upon, creating a hazardous conditionwhen entering or leaving the vehicle.(correct by inspecting and replacing allsuspect cab steps with improved steps.)
DEFECT #5 - VEHICLE SPEED CONTROL:LINKAGES
Posted on: 1979-10-12
Description

This could cause the accelerator to bind in position, resulting in loss of control over vehicle speed.
Consequence
Corrective Action
Dealer will relocate the accelerator linkage at no cost to owner.
Notes
Vehicle description: heavy trucks.system: throttle linkages and control; accelerator relay shaft.consequences of defect: binding of the accelerator could occur without priorwarning, causing loss of vehicle control and an accident.
