The short answer

NHTSA received MACK TRUCKS, INC.’s report on Apr 26, 2002. 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?

BOLTS TORQUED BELOW SPECIFICATION WILL NOT RELIABLY PREVENT AIR LEAKAGE AT THE AFFECTED ABS VALVE PACKAGE INTERFACE JOINTS ONCE THE COMPONENT BEGINS NORMAL VEHICLE OPERATION. IF AIR LEAKS DEVELOP AT ANY OF THE ABS VALVE PACKAGE INTERFACE JOINTS, BRAKE SYSTEM PRESSURE REDUCTIONS COULD OCCUR DURING BRAKING OR NORMAL OPERATION WITH UNITS EQUIPPED WITH THE TRACTION CONTROL OPTION, POTENTIALLY EXTENDING STOPPING DISTANCES, POSSIBLY RESULTING IN A VEHICLE CRASH.

ON CERTAIN TRUCKS EQUIPPED WITH MERITOR WABCO PNEUMATIC ANITLOCK BRAKE SYSTEM (ABS) VALVE PACKAGES, THE ASSEMBLY BOLTS ON THESE VALVE PACKAGES WERE NOT TIGHTENED CORRECTLY.

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.
