Defect description
VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE AIR SUSPENSION CONTROL VALVE SUPPLY LINE WAS NOT PLUMBED THROUGH AN AIR PRESSURE PROTECTION VALVE. IN THE EVENT OF A FAILURE, THERE WOULD BE LOSS OF AIR PRESSURE IN THE 'B' SYSTEM AIR RESERVOIR THAT SUPPLIES AIR PRESSURE FOR THE FRONT STEER AXLE BRAKES.
Safety risk
THIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.
Manufacturer remedy
DEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH AFTERMARKET ALUMINUM DUAL WHEELS, 22.5X8.25, ONE-PIECE, TUBELESS, SUPPLIED BY ACCURIDE/AKW. CERTAIN DESIGN REVISIONS COMBINED WITH PROCESS CONDITIONS CAUSED FATIGUE CRACKS IN THESE WHEELS.
VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE STEER AXLE WHEEL BEARING JAM NUT LOCK WASHER MAY NOT HAVE BEEN BENT OVER THE JAM NUT AFTER THE WHEEL BEARINGS WERE ADJUSTED.
Safety risk
IF THIS CONDITION EXISTS, THE JAM NUT AND WHEEL BEARING ADJUSTING NUT CAN BACK OFF THE SPINDLE ALLOWING THE WHEEL AND THE BRAKE DRUM ASSEMBLY TO SEPARATE FROM THE VEHICLE INCREASING THE RISK OF A VEHICLE CRASH.
Manufacturer remedy
DEALERS WILL INSPECT THE STEERING AXLE WHEEL BEARING JAM NUT LOCK WASHER TO DETERMINE IF IT IS BENT OVER THE JAM NUT, AND IF NOT, REPAIR AS REQUIRED.
