The short answer

NHTSA received MACK TRUCKS, INCORPORATED’s report on Jul 8, 1981. Copied from NHTSA on Oct 20, 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 INVOLVED TRUCKS HAVE PITMAN ARMS WITH TIMING MARKS AND SERRATIONS LOCATED 8 DEGREES OUT OF PROPER ALIGNMENT.

WHEN THE CHASSIS IS RAISED TO THE MAXIMUM CONDITION WITH THE WHEELS SUSPENDED OR DROPPED INTO A DEEP HOLE, THE PITMAN ARM AND DRAG LINK CAN GO INTO TOGGLE POSITION.

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.
