Remedy: Replace left hand control arm linkage assembly.
Model years: 1989
-
Shaft sector (steering)
Interference between steering gear sector shaft and the frame rail through hole can cause sector shaft wear and can weaken shaft cause it to break.
Remedy: Enlarge frame rail through hole to prevent interference: replace steering gear sector shaft if scored.
Model years: 1989
-
Linkages (steering)
Crack may develop on steering arm that could progress and reduce the fatigue life of the steering arm.

If these capscrews are damaged to the point that they allow the compressor back plate to dislocate from the turbocharger…
Remedy: Dealer will install a shield for the heads of the four capscrews, along with stronger sae 8 grade 8 capscrews, if necessary, at no cost to owner.
-
Steering wheel/handle bar (steering)
In the involved trucks it is possible the adjustable steering column rear mounting bracket could fail, allowing steering wheel assembly to fall down onto the operator"s lap.
Remedy: Dealer will install an additional bracket in this area to prevent the steering wheel from dislocating in the event of a bracket failure.
-
Steering wheel/handle bar (steering)
An improper pinch bolt and nut may have been used in the clamping of the steering shaft to the steering gear input shaft. Due to clamping force loads applied at the bolt, the nut could yield, resulting in looseness of the input shaft yoke. Should this condition go unnoticed, spline wear could cause shaft separation.
Remedy: Vehicles will be inspected and, if necessary, the correct fasteners will be installed at no charge to owner.
-
Multiple axle (suspension)
A casting deficiency exists in the lower section of the caps resulting in a reduction in the thickness of the material. Failure of a cap can allow the end of the rear spring to detach from the axle housing.
Remedy: Dealer will inspect and, if necessary, replace any of the spring insulator caps found to be defective. This will be done at no cost to owner.
-
Hanger/bracket (suspension)
The steel brackets on the suspension beam were found to be deficient due to excessive shrinkage and low mechanical properties. Failure of one or both of these brackets could cause a separation of the axle housing from the suspension.
Remedy: The dealer will inspect and, if necessary, replace any suspect bogie spring insulator caps with new caps meeting the proper specifications at no cost to owner.
Model years: 1978
-

This constitutes a non-compliance to federal motor vehicle safety standard no. 121, "air…
Remedy: Dealer will install new wheel speed sensors that incorporate improved wiring and the present bogie anti-wheel lock system will be changed to an axle-to-axle system for improved reliability.
-
Arm (steering)
The existing cross steering arms may have insufficient fatigue life in the neck area. This is near the boss for the cross steering tube ball joint connection. Failure of either of the cross steering levers could lead to loss of steering control of the right front wheel.
Remedy: The dealer will inspect and, if necessary, install cross steering arms of improved design and greater strength.
-
Service brakes, air: control unit/module
An axle "no brake" condition could result from an eaton controller internal electrical malfunction. This condition may cause the anti-wheel lock valve solenoid to be continuously energized and prevent the brakes from being applied on one of the axles. As a result, the anti-wheel lock warning lamp is not activated.
Remedy: The dealer will inspect and, if necessary, replace the anti-wheel lock controller without charge to owner.
-
Gasoline (engine and engine cooling)

-
Anchorage (seat belts)
The involved vehicles do not conform to federal motor vehicle safety standard no. 209, "seatbelt assemblies". Although the seatbelts in question performed marginally with respect to the 5000 lb. Load requirement, additional testing confirmed that the anchor could fail, allowing either the anchor to slip over the hold-down nut or the…
Remedy: Dealer will inspect and, if necessary, replace seat belt assemblies without charge to owner.
Model years: 1977
-
Wheels
The front wheel rim clamp studs, installed on the involved vehicles, may not have been manufactured correctly, causing a brittle condition in the thread root area. The studs could eventually crack and break when wheel nuts are tightened to specifications.
