The short answer

NHTSA received MACK TRUCKS, INCORPORATED’s report on Jan 12, 1979. Copied from NHTSA on Oct 26, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

The notice gives no hazard in a field of its own.

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.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
