The short answer

NHTSA received MACK TRUCKS, INCORPORATED’s report on Nov 1, 1993. Copied from NHTSA on Oct 24, 2026.

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

What’s wrong with it?

PILLOW BLOCK FAILURE ALLOWS THE DRIVELINE (JACKSHAFT)TO DROP DOWN ONTO THE ROADWAY AND CREATE A SAFETY HAZARD TO OTHER VEHICLES.

THE DRIVESHAFT TO THE FRONT DRIVING AXLE IS SECURED TO A BRACKET USING TWO PILLOW BLOCKS.

THESE BLOCKS ARE OF INSUFFICIENT STRENGTH TO SUPPORT THE DRIVESHAFT AND COULD FAIL.

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.
