-
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.
-
Fan (engine and engine cooling)
The flex blade fans on the involved vehicles may develop cracks in the laminated stiffener as a result of fatigue during operation. If such a condition exists and the cracks go undetected, continued operation could cause pieces of the stiffener to break off.
Remedy: Dealer will replace the original fan with a steel fixed blade fan, free of charge.
-
Gear box (other than rack and pinion) (steering)
The lower steering shaft yoke clamp bolts on the involved vehicles may not have been sufficiently tightened. Should these bolts lossen and come off, the lower steering shaft could separate from the steering gear.
Remedy: The dealer will secure the clamp bolt and make the necessary modifications on the lower steering shaft, free of charge.

How do I know if my 1974 Mack Ws has an open recall?
Enter your 17-character VIN above. The VIN is on the driver's side dashboard (visible through the windshield), the driver's door jamb sticker, and your registration or insurance card. The check runs against NHTSA's live database and tells you which campaigns list your vehicle. 7 campaigns currently list the 1974 Mack Ws; your car may already have been repaired under some of them.
Is the recall repair free?
Yes. Under federal law, manufacturers must fix safety recalls at no charge for vehicles up to 15 years old from the date of sale to the first owner. Contact any authorised Mack dealer with your VIN and the NHTSA campaign number (for example 75V060000).
What is the difference between a recall and a complaint?
A recall is a safety campaign filed by the manufacturer or ordered by NHTSA, with a defined defect and remedy. A complaint is a report an owner sent to NHTSA; it is not verified, but patterns of complaints are what trigger NHTSA investigations and, eventually, recalls.
