For the 1979 Mack FM. These apply to the model and year, not to one particular vehicle: check your VIN to see whether yours is included and whether it has been repaired.

Has your Mack been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Mack dealer can also check your VIN. Recall repairs are free.

1979 Mack FM recalls, newest first

Suspension › Rear › Springs › Leaf spring assembly

Summary: The spring seat plate, located between the axle housing and the suspension springs, may deform due to spring bending. As a result, the clamping force in the assembly may be reduced. Loss of clamping force could cause spring failure and the axle will dislocate. Also, the tire could come into contact with the spring.
Remedy: The dealer will replace the existing spring seat with a newly fabricated seat which is welded to the housing. An improved spring clamping plate and new springs will also be installed without charge.
