The short answer

NHTSA received MACK TRUCKS, INCORPORATED’s report on May 23, 1988. 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?

IF CLAMP PLATE BREAKS, YOKE WOULD FLY OFF AT DETACHEDPOINT AND COULD INJURY ANYONE STRUCK BY FLYING FRAGMENTS. ALSO, THE DETACHEDINNER SHAFT COULD INTERFERE WITH THE BRAKE SYSTEM AIR SUPPLY HOSES AND TRACTORTIRES, WHICH COULD RESULT IN LOSS OF TRUCK CONTROL AND AN ACCIDENT.

CLAMP PLATES USED BETWEEN THE DRIVE SHAFT AND CARRIER YOKES MAY CRACK AND COULD BREAK DUE TO IMPROPER HEAT TREATMENT.

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.
